The curve intersection routine currently implemented follows the paper by 'Koji Nakamaru and Yoshio Ono'. The maximum recursion depth computed as a part of the intersection routine in line 149 (https://github.com/mmp/pbrt-v3/blob/master/src/shapes/curve.cpp#L149) actually has a probable bug.

The original paper computes r0 = sqrt(2) * N(N-1) * L0 / (8 * epsilon). Since we assume only cubic Beziers, N = 3 here and hence N*(N-1) actually would be 6 . However the current code has 12 which might result in a larger recursion depth being computed than what is necessary. Increased recursion would not result in an error, however might result in wasted computation.

If the InfiniteAreaLight constructor is modified to create a low-res environment map with only the top scanline emitting like this:

          resolution.x = resolution.y = 10;
          for (int y = 0; y < resolution.y; ++y) {
            for (int x = 0; x < resolution.x; ++x) {
              if (y == 0)
                texels[y * resolution.x + x] = 1000000.;
              else
                texels[y * resolution.x + x] = 0.;
            }
          }

Then if a small test like this is performed:

    for (Float y = 0; y < 1.f; y += .0249f) {
      for (Float x = 0; x < 1.f; x += .125f) {
        fprintf(stderr, "(%f, %f) = %f\n", x, y,
                Lmap->Lookup(Point2f(x, y)).y());
      }
    }

Then for lots of y values close to 1, the lookup returns a non-zero result:

(0.625000, 0.996000) = 494165.437500

For high-res environment maps, this issue is hidden by the fact that the sinTheta value that the environment map luminance is multiplied by when creating the sampling PDF is very small. But this is still bad.

The root issue is that we want the MIPMap to use REPEAT (as it does now) for out-of-bounds s coordinates, but to do a mirror and flip combination for out of bounds t. Unfortunately, MIPMap only supports one wrap mode. The right fix is probably to rewrite InfiniteAreaLight to not use MIPMap at all, since we don't need most of its functionality anyway.

Also, we should add a unit test for this when it's fixed.

Hi, just wondering what the intuition is behind CorrectShadingNormal in BDPT.cpp, line 54. I gather that it is to compensate for the potential difference in normals due to phong interpolation, but I cannot find any sources in the literature about such a correction coefficient. Why is it only needed to light traced paths?

Thanks,

InitProfiler() should set up a periodic timer to interrupt all currently running threads and call ReportProfileSample() each time it fires. It looks like Waitable Timer Objects (https://msdn.microsoft.com/en-us/library/ms687012(v=VS.85).aspx) are what we want.

The following lines in CMakeLists.txt create a version of pbrtlex.cpp that does not compile on Windows (with MSVC 2015). Two of the issues encountered are:

• The escape character () in the inline bash statement (bash -c ...) is not needed
• The generated pbrtlex.cpp contains references to unistd.h and is generally unusable.

Removing the IF(BISON_FOUND AND FLEX_FOUND) part of the conditional fixes the build.

As explained in Section 14.6.5 and Figure 14.13, p.726 in PBRT v2 the importance of the environment texture should be computed by interpolating adjacent texels. Therefore InfiniteAreaLight samples the texture at the discrete coordinates uv. However, this means that the pdf in Distribution2D for uv represents the average importance for the area (uv-0.5, uv+0.5). Now, SampleContinuous selects a bin according to the pdf and samples uniformly within that bin, i.e. the returned coordinates represent [uv, uv+1.0). To account for this difference in coordinates the Sample_Li and Sample_Le functions of the infinite area light should subtract "half a texel" from uv, e.g.:

--- a/src/lights/infinite.cpp
+++ b/src/lights/infinite.cpp
@@ -98,3 +98,5 @@ Spectrum InfiniteAreaLight::Sample_Li(const Interaction &ref, const Point2f &u

+    uv.x -= (Float)0.5 / Lmap->Width();
+    uv.y -= (Float)0.5 / Lmap->Height();

So, Figure 14.13 is actually misleading, because for textures their values are defined at the center of each texel (at continuous coordinates uv+0.5, see Section 10.4.3, p.538): the piecewise linear function should therefore be shifted by 0.5.

The error is subtle and only gets noticed for high-contrast environment maps. For example, using a black texture with only one white texel, half of the samples are wasted (they have zero contribution). A nice way to debug these issues is to visualize the sample contributions of the infinite area light, i.e. render L = infiniteLight->Sample_Li(...) / lightPdf using the (normalized) pixel coordinates as random numbers. The more constant the resulting image, the better the importance sampling.

Some more remarks on minor issues:

• The environment texture is resampled by MIPMap to a power-of-two resolution. To avoid aliasing artefacts the importance map should be created with that resolution as well (that's why the above patch uses Lmap->Width() and Lmap->Height()):

• Because we want to compute the average importance for the area (uv-0.5, uv+0.5) the average of sinTheta is better approximated with "sin(uv)":

  This leads to zero probability for the first row, which is actually a good thing: uv cannot become negative after subtracting half a texel. And sampling the north pole leads to artefacts anyway (because of texture wrapping light leaks from the south pole).

• The computation of the filter width could be skipped. The default width of zero in MIPMap::Lookup already ensures that the most detailed mipmap level is used, and the triangle filter used for bilinear interpolation computes the wanted average of the four texels.

I was confused in that switch / fall break, then I notice that in PBRT source code from book 2, you have a comment that helps understand the fall and make the things more clear.

Just compiled and ran a test using a VS2015RC build on my branch 'appVeyor'. Results look not so good, any hints that I might want to look at ?

104 FAILED TESTS

I've done some benchmarks of a parallel scalability on a 16 core machine, using 1, 2, 4, 8, and 16 threads (for all of the integrators besides Whitted and direct lighting). This spreadsheet summarizes the results (for the moderately complex "breakfast" scene, to come in the pbrt-v3 scenes distribution). For the benchmarks, I modified Film:WriteImage() to return immediately, so that the time measured in the Render() methods didn't include that time.

Interestingly enough scalability for everything but SPPM is very nearly the same: a not impressive 1.9x with two cores, up to ~12.7x with 16 cores. SPPM is broken into the camera pass, photon pass, and statistics update pass; there, scalability is slightly worse. (Though for SPPM there is some construction of and updating of shared data structures, so it's reasonable that it's a bit worse...)

I'm building pbrt-v3 under Arch Linux x86_64, gcc 5.2.0, and it won't build. It says in the function ParallelFor() in parallel.cpp.o in libpbrt.a there's an undefined reference to 'pthread_create'. I tried editing CXXFLAGS in CMakeFiles/pbrt.dir/flags.make and adding -pthread, then I tried -lpthread, same problem. It might be I'm just doing something wrong, but then, it should work without me messing with the makefiles anyway, shouldn't it? Thanks in advance!
(By the way, I'll copy the whole error log here if it might help:

The SampledSpectrum class uses the function AverageSpectrumSamples to average the loaded spectra from .spd files. This function gives a wrong spectrum in case of monochromatic SPDs that are sampled with 1 nm resolution. For example a laser beam that is delta Dirac, or has only certain intensity at one wavelength. This function splits the value between two wavelengths, which is completely wrong and can significantly change the results of the rendering.

To reproduce the error, just set
static const int sampledLambdaStart = 400;
static const int sampledLambdaEnd = 700;
static const int nSpectralSamples = 300;

and load the .spd file that has a monochromatic spectrum (1000 at 650 nm, given below)
If you print the values of the resulting spectrum, you will get the following result
...
at[649] = 0
at[650] = 500
at[651] = 500
at[652] = 0
...

However, you should get the following
...
at[649] = 0
at[650] = 500
at[651] = 0
at[652] = 0
...

Proposed solution:
Add one more argument to the AverageSpectrumSamples that reflect the index of the wavelength, and then check if the spectrum has sampling of 1 nm or not. If yes, then return the power at the given index, otherwise, average the spectrum.

Float AverageSpectrumSamples(const Float *lambda, const Float *vals, int n, Float lambdaStart, Float lambdaEnd, const int index)

if ((sampledLambdaEnd - sampledLambdaStart) == nSpectralSamples) return vals[index];

Trying to render a scene with an AreaLightSource fails and gives me sort or a reddish image

I am using the following light source

Light

AttributeBegin
AreaLightSource "area"
"color L" [1 1.0 1.0]
Translate 0.0 1.0 0.0
Rotate 90.0 1.0 0.0 0.0
Shape "disk"
"float radius" [0.1]
AttributeEnd

I have checked the samples uploaded on pbrt.org, but there are no samples with AreaLightSource.

The simplified pseudo code for the "translucent" material is this:

bsdfs.add( new LambertianReflection( reflectance * diffuse ) );
bsdfs.add( new LambertianTransmission( transmittance * diffuse ) );

var microfacetDistribution = new TrowbridgeReitzDistribution( roughness, roughness );
var fresnel = new FresnelDielectric( 1, 1.5 );
bsdfs.add( new MicrofacetReflection( reflectance * specular, microfacetDistribution, fresnel ) );
bsdfs.add( new MicrofacetTransmission( transmittance * specular, microfacetDistribution, 1.0, 1.5 ) );

You can see that roughess is only used for the specular. But if one assumes a microfacet model of the surface for specular, shouldn't one similarly assume microsurface model for the diffuse?

Second issue, doesn't this lead to a microfacet model conflict: Oren-Nayar model is derived from the older Cook-Torrence / Beckmann microfacet distribution. But the specular model here is based on the more modern Trowbridge-Reitz microfacet distribution. Thus there may be a roughness parameterization conflict between these two models as it is -- although it also may be so slight it doesn't matter, or maybe diffuse roughness in this case has no perceptible result?

I am using the pbrt-v3 bvh.cpp ported to my raytracer and i am building it on linux and windows (mingGW) on Linux all SPLIT methods work, on Windows, the SAH is giving me problems..
Apart that I could still have issues in my ported source code, I was looking and found that in this line in original source:

https://github.com/mmp/pbrt-v3/blob/master/src/accelerators/bvh.cpp#L356

I was expecting that it "return node;" at that point, since it just created a leaf. As it is now, it will fall and init an interior that I believe it is not correct.

Hello, I am new to pbrt, just start to try it, I wanna render an animation sequences, maybe 150 frames, how do I set the related setting in the scene file? Hope someone can give me a guide?
Thanks!

When specifying a Films image filename with the .pfm extension, PBRT will state that the image format is not supported.

This due to an implementation error, where the code which checks the extension is incorrect:

Original code

if (HasExtension(name, ".exr")) {
    WriteImageEXR(name, rgb, resolution.x, resolution.y, totalResolution.x,
                  totalResolution.y, outputBounds.pMin.x,
                  outputBounds.pMin.y);
} else if (HasExtension(name, ".exr")) {
    WriteImagePFM(name, rgb, resolution.x, resolution.y);
} 

Fixed code

if (HasExtension(name, ".exr")) {
    WriteImageEXR(name, rgb, resolution.x, resolution.y, totalResolution.x,
                  totalResolution.y, outputBounds.pMin.x,
                  outputBounds.pMin.y);
} else if (HasExtension(name, ".pfm")) {
    WriteImagePFM(name, rgb, resolution.x, resolution.y);
} 

See Per Christensen's report for pbrt-v2 in mmp/pbrt-v2#52. pbrt-v3 has the same issue (even though the code was rewritten :-( ).

I think there are a few small issues with the flex and bison stuff in CMakeLists.txt.

• I think the outputs of bison should also include pbrtparse.hh.
• Bison is annoying, since on some platforms it uses .hh for the suffix of the generated header file, on others it uses .hpp, etc. pbrtlex.ll #includes pbrtparse.hh. Before, the makefile would check the suffix generated by bison and rename the header file if needed (

  pbrt-v3/src/Makefile

  Line 153 in 8e23330

  @if [ -e core/pbrtparse.cpp.h ]; then /bin/mv core/pbrtparse.cpp.h core/pbrtparse.hh; fi

  ).
• The output of the bison rule should probably be named pbrtparse.cpp, rather than pbrtparser.cpp, for consistency with the naming of the .yy file.
• I think but am not sure that the flex rule needs an explicit dependency to the pbrtparse.hh output of the bison rule so that it doesn't try to compile pbrtlex.cpp before the bison rule has run. (I'm not positive about this; maybe flagging the .hh output is enough.)
• Is it definitely the case that when running the flex/bison rules, the pbrtparse.hh generated by bison (vs the one checked into src/core) is used? It'll be a really ugly/hard to chase down bug if the user has made modifications to the .yy file but then the wrong header is used.

(CC @nyue )

The following code in bvh.cpp causes a compile error (C1506: unrecoverable block scoping error) in VS2013:

struct BucketInfo {
  int count = 0;
  Bounds3f bounds;
};

This can simply be fixed by moving the struct definition out of the function definition.

Changing the Spectrum to be of type SampledSpectrum in pbrt.h gives few compilation errors due to the MIPMap class.

// typedef RGBSpectrum Spectrum;
typedef SampledSpectrum Spectrum;

Fabrice Rousselle reported the following issue:

I've run into a strange bug with PBRT that I believe is actually a tinyexr one. I was rendering a 33x33 image of the cornell box scene and the bottom line of pixels was garbage. It worked fine for 32x32 or 34x34 images though. Looking into it some more, I tried with other sizes and it seems that anything smaller than 10x10 pixels produces garbage for the whole image plane. The content of the buffer though is valid up to the point that it's passed to the SaveMultiChannelEXRToMemory method.

I suspect that the bug is due to the ZIP compression of tinyexr, but it's not clear to me how to disable the compression in the code, so I couldn't verify it. The latest version of tinyexr on github is also quite different from the one in pbrt-v3 (it's now a single header file), and I didn't try it either.

If you know a way of disabling the compression, I would be very interested, otherwise I'll try using ILM's OpenEXR library instead for now.

I'm attaching my fancy cbox.pbrt file which produces a 3x3 rendering if you want to reproduce the issue (maybe it's linux specific?), as well as the exr files I obtained at 3x3 and 33x33 resolutions.

The attachment is a Base64 encoded zip file (GitHub file upload only allows a few file formats like PNG and PDF and doesn't like ZIP):

Archive.txt

Attached are images of sanmiguel_cam25.pbrt with 2k Halton samples with both the path tracer and the BDPT integrator. Note that the images are significantly different (note e.g. flowerpots and the railing on the top balcony, the checkered tablecloth on the table under the nearest ground floor arch, etc.)

(Note also some big noise spikes in the BDPT image, though that's potentially a different issue.)

If I disable MIS by changing MISWeight() in bdpt.cpp to just return "1.f / (s + t - 1)", then I get the bdptnomis.exr image (that one was rendered with 16k spp). It seems to do much better on those features, but it still doesn't match the path tracer (though maybe this is just too many massive noise spikes). (Thus, the issue may be related to #69.)

sm25.zip

Currently, all of the materials are specified right before their meshes. It'd be better to emit all of them at the start, as NamedMaterials, which would make it easier to edit/tweak them.

Installing pbrt currently includes build binaries and the static library only. For compiling against pbrt library from other programs, we need the header files of pbrt.

Possible solution: change CMakeLists.txt s.t. all source header files located in ./src/ are copied to include/pbrt/ which preserves directory structure. This is done by appending

INSTALL ( DIRECTORY src/
  DESTINATION include/pbrt
  FILES_MATCHING PATTERN "*.h"
  )

to CMakeLists.txt. All relevant header files should be included. I locally extended it this way and it works. Further usage details: http://www.cmake.org/cmake/help/v3.2/command/install.html

This is not an important issue, but I was looking at the code for the BxDF creation in the materials. I noticed patterns like this (pseudo code):

// creation of translucent
if( diffuse !== BLACK )
    if( reflectance !== BLACK )
        bsdfs.add( new LambertianReflection( reflectance * diffuse ) );
    if( transmittance !== BLACK )
        bsdfs.add( new LambertianTransmission( transmittance * diffuse ) );

if( specular !== BLACK )
    var microfacetDistribution = new TrowbridgeReitzDistribution( roughness, roughness );
    if( reflectance !== BLACK )
        var fresnel = new FresnelDielectric( 1, 1.5 );
        bsdfs.add( new MicrofacetReflection( reflectance * specular, microfacetDistribution, fresnel ) );
    if( transmittance !== BLACK )
        bsdfs.add( new MicrofacetTransmission( transmittance * specular, microfacetDistribution, 1.0, 1.5 ) );

If one allowed for BxDFs to state if they are useless, by using looking at their parameters, one could simplify the above to something much more straight forward:

// creation of translucent
bsdfs.add( new LambertianReflection( reflectance * diffuse ) );
bsdfs.add( new LambertianTransmission( transmittance * diffuse ) );

var microfacetDistribution = new TrowbridgeReitzDistribution( roughness, roughness );
var fresnel = new FresnelDielectric( 1, 1.5 );
bsdfs.add( new MicrofacetReflection( reflectance * specular, microfacetDistribution, fresnel ) );
bsdfs.add( new MicrofacetTransmission( transmittance * specular, microfacetDistribution, 1.0, 1.5 ) );

bsdfs.removeUselessBxDFs();

Basically one could encapsulate into each BxDF class its ability to optimize itself out of the computation. It is sort of weird that in the creation of the materials one is trying to optimize some BxDFs away, because the material itself is basically trying to understand the internals of the BxDFs and their dependences upon parameters. One could just encapsulate that decision of whether the BxDF is useless into the material -- probably where it should be.

But then this requires a filtering of the created BxDFs after creation to remove the useless ones, or it requires helper per BxDF factory functions to do conditional creation of BxDFs. Either way, the code would be cleaner with less breaking of the BxDF encapsulation within the material creation, if that is important.

The default implementation of the AddSampledSpectrumFiles assumes that all the loaded .spd files match with the hard-coded parameters in the spectrum.h file that ranges, by default, between 300 and 700 nm. So, if the given .spd file contains a different range, then the obtained spectrum is no more valid.

I have tried to go for a quick solution that checks the range of the given wavelengths in the .spd file and those in the spectrum.h file and get the right mapping between them.

In paramset.cpp

void ParamSet::AddSampledSpectrumFiles(const std::string &name,
                                       const char **names, int nValues) {
    EraseSpectrum(name);
    std::unique_ptr<Spectrum[]> s(new Spectrum[nValues]);
    for (int i = 0; i < nValues; ++i) {

The unit tests for incorrect re-intersections with spawned rays for Cone and Paraboloid fail (currently commented out in src/tests/shapes.cpp). This should be chased down; could be related to a bug in the EFloat class, since those lean heavily on that (vs the other shapes where the re-intersection tests all pass.)

The current implementation is based on maintaining an interval, which is fine, but has diverged (already) from the book text.

Krämer's paper "A priori worst-case error bounds for floating-point computation" (http://www.acsel-lab.com/arithmetic/arith13/papers/ARITH13_Kramer.pdf) outlines how to compute bounds using a computed value and an error interval; it would be nice to use his method to fix the bugs that caused the original shift to the interval-based approach (46de256) and get things back in better sync with the book text.

Hi!

I'm trying to build a DEBUGGING version of pbrt-v3 in GNU/Linux (g++ 5.3, but tried older versions).

I obtain errors regarding the 'struct { EndpointInteraction ei; MediumInteraction mi; SurfaceInteraction si; };' in bdpt.h, since members with constructors and copy assigment operators are not allowed in anonymous structs in C++

Release mode is Ok since a union is used instead of the struct.

Hi,

I tried pbrt-v3 on Windows, and there're 2 build issues:

1. bash command in CMake does not work well on Windows:
   COMMAND bash -c "if [[ -e ${CMAKE_BINARY_DIR}/pbrtparse.hpp ]]\; then /bin/mv ${CMAKE_BINARY_DIR}/pbrtparse.hpp ${CMAKE_BINARY_DIR}/pbrtparse.hh\; fi"
   The command below works, and it should be portable to Linux and OSX:
   COMMAND ${CMAKE_COMMAND} -E rename ${CMAKE_BINARY_DIR}/pbrtparse.hpp ${CMAKE_BINARY_DIR}/pbrtparse.hh
2. The project can't build with VisualStudio2012, which does not have header file cinttypes. VisualStudio2015 works for me.

Clean checkout of master
execute 'make' in directory 'src'.

It looks like two main errors:

1. GCC 4.7 is not able to disambiguate void(int) from void(int, int) in the template parameter of ParallelFor.
2. From a quick glance at the GridDensityMedium class it looks like you've got a non-default constructor defined but do not explicitly declare the move assignment operator. I haven't tracked it down yet but it looks like there's an assignment somewhere that GCC 4.7 is not converting to a move and the unique pointer is preventing that.

In current volpath loop logic, it cannot reproduce single scattering light path accurately(only one scattering event in the medium).

Please see 7.1 Analytical Single Scattering Solution in
"Evaluation of Visual Parameters in Volumetric Path Tracing"
for the scene setup: http://www.diva-portal.se/smash/get/diva2:796154/FULLTEXT01.pdf
(The scene is one cube([-1, 1]^3) lit by parallel light(0, -1, 0) and seeing it from Z direction)

(From left to right: PBRT-v3, Mitsuba 0.5 and the analytic solution)

Mitsuba and analytic single scattering solution gives correct result, but PBRT-v3 gives a bit brighter result.
(Note that I've changed to use pow(x, 1.0f/2.2f) in PBRT-v3's gamma correction for precise image comparison in LDR image format)

The situation of PBRT's volpath looks like

• maxdepth is set to 1
• First the ray hits the surface of the cube(no surface BSDF attached). volpath decrements bounces. bounces become -1.
• Next the ray samples the volume medium(bounces = 0). 0 <= maxDepth so the volpath continue to scatter the ray in the medium

Thus, theres 2 scattering events in the medium at max even maxdepth is set to 1. This would be the reason why PBRT-v3 result become brighter and cannot produce single scattering light path accurately.

One quick idea to solve the issue is to remove bounce-- line https://github.com/mmp/pbrt-v3/blob/master/src/integrators/volpath.cpp#L99
,but this may affect another light paths so I'm not sure this is OK or not.

Attached zip is the reproducing scenes in PBRT and Mitsuba, and also analytic solution code in C++.

The new image i/o unit tests in 023a483 revealed a fairly significant issue: for everything other than EXR, if you write out an image and read it back, you get an image that is flipped in y. (Why this is so is obvious upon inspection of the source code, where the various image reading routines do this flip.)

(And as such, if one has an image texture that is a PNG, say, and converts it to an EXR, the texture will be flipped!)

Just fixing this in the image i/o routines causes rendered images to change, as all textures end up flipped. I believe that the following definitions/conventions give a sensible (and not too disruptive fix):

• Fix the image i/o routines so that they behave sensibly, and give you back the pixels you gave it, in the same order (modulo image format dynamic range and precision limitations).
• Enshrine the definition of image coordinates to have (0,0) be the upper left--as is already clearly defined in raster space for cameras, for example
• Clearly define texture space to have (0,0) to be in the lower right--this is in line with both pbrt's current behavior for image maps as well as with OpenGL's convention, for example. (And thus, do an explicit mirroring in the y direction for image maps and image maps only.)
• However, define infinite area light coordinates to be in terms of (theta,phi) w.r.t. the up direction, so that (0,0) is pointing up for them.

This almost exactly matches current behavior, with the exception that any EXR images that are used as ImageMaps will be flipped. However, this seems a small price to pay for consistency.

I was wondering why the current implementation of Oren-Nayar microfacet model of diffuse reflection does not allow for a similar Oren Nayar transmission BxDF? I think theoretically it should be possible to have Oren-Nayer transmission?

There is a LambertianReflection and a LambertianTransmission BxDFs, but the OrenNayer BxDF appears to only be Reflection.

I mention this in part because the Oren-Nayar "sigma" parameter for adjusting diffuse roughness is only used by the Matte material and not on the Translucent material, even though both attempt to model a diffuse component.

Using static code analysis tools (e.g. MSVC's /analyze) on the code

Coverity http://www.coverity.com would be a good candidate as an online static code analysis. Its free for open source software and has an Travis CI integration.

The documentation of Coverity with Travis CI is here

https://scan.coverity.com/travis_ci

If the two transformations given to it have a mirroring between them (i.e. differing signs in some components), then the motion bounds it computes are incorrect; this can be seen by removing the three std::abs calls in t = t * Scale(std::abs(r()), std::abs(r()), std::abs(r())); in src/tests/animatedtransform.cpp.

This is admittedly not a common case, but would be nice to handle correctly.

These two code patterns (here as pseudo code) are used a lot in the creation of the materials:

var isSpecular = ( uRoughness === 0 && vRoughness === 0 );
if( isSpecular )
    bsdfs.add( new SpecularReflection( reflectance, fresnel ) );
else
     bsdfs.add( new MicrofacetReflection( reflectance, microfacetDistribution, fresnel ) )

And

var isSpecular = ( uRoughness === 0 && vRoughness === 0 );
if( isSpecular )
    bsdfs.add( new SpecularTransmission( transmittance, 1, ior, mode ) );
else
     bsdfs.add( new MicrofacetTransmission( transmittance, microfacetDistribution, 1, ior ) )

I view these two patterns as optimization at the wrong level of abstraction. I would suggest instead that inside MicrofacetTransmission it knows how to use the logic of the optimized SpecularTransissiion BxDF when roughness is 0, or there is a factory function that will return a SpecularTranmission BxDF when the roughess parameters are 0.

Then you can implement this optimization pattern once in a central location and then it is applied everywhere, rather than just in the materials where one remembers to do this roughness dependent switching between these two BxDFs.

If one did this change and the one suggested in #29, the glass material would be simplified from:

var isSpecular = ( uRoughness === 0 && vRoughness === 0 );

var microfacetDistribution = null;
if( ! isSpecular )
    microfacetDistribution = new TrowbridgeReitzDistribution( uRoughness, vRoughness );

if( reflectance !== BLACK )
    var fresnel = new FresnelDielectric( 1, ior );
    if( isSpecular )
        bsdfs.add( new SpecularReflection( reflectance, fresnel ) );
    else
        bsdfs.add( new MicrofacetReflection( reflectance, microfacetDistribution, fresnel ) )

if( transmittance !== BLACK )
    if( isSpecular )
        bsdfs.add( new SpecularTransmission( transmittance, 1, ior, mode ) );
    else
        bsdfs.add( new MicrofacetTransmission( transmittance, microfacetDistribution, 1, ior ) )

To just the very clear and concise:

var microfacetDistribution = new TrowbridgeReitzDistribution( uRoughness, vRoughness );
var fresnel = new FresnelDielectric( 1, ior );
bsdfs.add( new MicrofacetReflection( reflectance, microfacetDistribution, fresnel ) );
bsdfs.add( new MicrofacetTransmission( transmittance, microfacetDistribution, 1, ior ) );

Which to me would be a major improvement for readability, clarify and for maintenance.

I was trying to render San Miguel scene (environment lightmap RenoSuburb01_sm.exr needed a conversion because of tinyexr limited compression support) with the new bdpt integrator, the no-crop one looks okay but once I applied a crop, the rendering looks undersampled especially in the lower half, the cropwindow applied was [ 0.25 0.75 0.25 0.75 ]. I tried to switch to the path integrator and the undersampled symptom persisted. (same on both OSX and VS2015)

The default implementation of the AddSampledSpectrumFiles assumes that all the loaded .spd files match with the hard-coded parameters in the Spectrum.h file that ranges, by default, between 300 and 700 nm. So, if the given .spd file contains a different range, then the obtained spectrum is no more valid.

I have tried to go for a quick solution that checks the range of the given wavelengths in the .spd file and those in the spectrum.h file and get the right mapping between them.

Hey,

I've been reading through the implementation of Photon Beam Diffusion (which is a really nice upgrade over the dipole in pbrt-v2 by the way), while comparing it to the paper and the Matlab reference implementation. I still have some questions about the code and I think I've found a few mistakes.

1. Is the normalization constant 1 / (4 * C_phi) missing in the BSSRDF? It seems that it was replaced by sigma_t which I can not find in the paper.
2. Are the 1 / pi term and the two F_t terms in the BSSRDF computed using the BSDF? You seem to both add a LambertianReflection (for the 1 / pi term, I guess) and a SpecularTransmission (for the F_t term), but when evaluating the BSDF this results in (1 / Pi + F_t) instead of 1 / Pi * F_t.
3. Why is the BSSRDF profile multiplied with 2 * Pi * r in ComputeBeamDiffusionBSSRDF? Is this needed for the Catmull-Rom interpolation?
4. Where is the second F_t term in the single scattering integrand? The reference Matlab implementation also seems to lack one of the F_t terms, but it seems to be the other one.
5. Shouldn't cosThetaS (in the single scattering integrand) always be equal to 1? The paper states that theta_i = arccos(-w dot n), so cos(theta_i) = -w dot n. w is the direction of the light beam, which is orthogonal to the surface (and in the opposite direction of the surface normal), so w = -n, so -w dot n = -(-1) = 1.
6. You only seem to consider two intersections when sampling the BSSRDF, but there could be multiple intersections with the surface. It currently is possible that a point sampled using one axis cannot be sampled using a different axis (because it finds a different intersection first), but the PDF seems to assume that the same point is found using all axes. I think you should find all intersections and then randomly pick one, sadly this also requires you to find the intersections for the other axes in order to calculate the PDF.

Cheers,
Tom

First, the {NUMBER} rule in pbrtlex.ll converts all numbers to Floats, which in turn means that any integer > ~2^24 is rounded to the nearest float. It would be nice if they were left as integers. (This almost never matters, but is annoying.)

Second, it'd be nice to support hexadecimal floating-point values.

The following pbrt file will reproduce the crash:

You'll also need the ceramic.bsdf and room-teapot.pbrt which can both be found in pbrt-v3-samples.

room-teapot.pbrt looks like this:

for 2000 lines so I'm guessing it tries to allocate a fourier BSDF for each triangle which causes it to eat up memory.
