Hello,
When compiling the Anari SDK on Windows 11 Visual Studio 2019 I get this build error:

When building the project statically and then installing to CMAKE_INSTALL_PREFIX
, on Unix the anchoring logic that determines where to search for libanari_device_XXX.so
will base the search path off the folder that the executables are located in (i.e., bin
) and thus won't find the actual device library (which is installed to lib
). Therefore, static builds currently only work when being used from the build tree.
Need to move the anariGetObjectFeatures
and anariGetInstanceFeatures
definitions from the header file (anari_feature_utility.h
) to the appropriate implementation file (API.cpp
??). Having the definitions in the header file causes a multiple definition
error when trying to #include <anari/anari_cpp.hpp>
as the definitions will appear in multiple places and the linker doesn't like it.
Hi,
I'm trying to use the Python bindings, with an AMR spatial field extension. That extension requires the block data to be specified as a ANARI_ARRAY1D
of ANARI_ARRAY1D
(of ANARI_FLOAT32
). Myself being an absolute Python newbie, and with very little experience with the pyanari bindings, I wonder if someone could give me a pointer how to do this. For reference, some work in progress code that currently fails for me with memory access violations (upon setting those arrays) can be found here in this file:
Perhaps someone can point me to some example code showing how this is done. I'm currently working off the tutorial as well as the blender plug-in.
Is the code ported to Windows ?
I tried building it but came across this error

After installation of the SDK, the CMake config module exports targets anari::anari
, anari::helium
, and anari::anari_test_scenes
, but a corresponding target for the debug backend (anary_library_debug) seems to be missing.
A CMake target anari::anari_library_debug
for the debug layer would be useful because it would allow querying the install location of anary_library_debug.dll
. On the Windows platform, an application typically must copy all Anari DLLs to the application's runtime directory (where the .exe is located) so that they will be found at runtime. Having a CMake target for the debug lib would simplify this deployment step - even if the application does not link to this backend directly.
Trying to build, I attempted a few variations similar to the github workflow to get it working, but I always get the following syntax error:

Hello,
The Windows build completes fully. But when I run the 'viewer.exe' or 'anari_regression_tests.exe'
ANARI ERROR: 'environment' library selected but ANARI_LIBRARY is not set
Is this something missing from the environment variables?
Kind regards,
Cameron
The base type used for implementations is called anari::Device
, but the C++ bindings also use the symbol name anari::Device
which causes a conflict by redefining the type.
The getenv
function will return a NULL pointer if the environment variable is not set on the line:
Line 86 in c755452
libraryName
(and the reference name
) in the line:Line 93 in c755452
Line 104 in c755452
The ANARIFeatures struct is missing extension ANARI_KHR_STEREO_RENDERING
.
Is there documentation somewhere regarding implementing a new device ?
I'm working on a Vulkan device and I'm having a hard time grokking what should be in the device.json
file, as well as setting up the skeleton of the device implementation.
I am working with C and don't intend to use helium
.
Thanks.

Also, the there's no way to disable the render test, nor running them without installing the example device. It would be nice to either be able to disable them, or run the tests with the example device in the build folder.
Thanks
When building the latest ANARI SDK with BUILD_HELIDE_DEVICE:BOOL=ON
and using CMake 3.18 I get the error below with curl
(which does support the required protocols and was manually tested and successfully downloaded the embree file).
However, when using CMake 3.25.1 the ANARI SDK builds successfully. VisIt's automated build scripts currently use CMake 3.18 and are generally several CMake releases behind the current.
Just a heads up, I have added ANARI to microsoft/vcpkg so its a bit easier to build and use:
https://github.com/microsoft/vcpkg/tree/master/ports/anari
microsoft/vcpkg#33213
I am currently adding OptiX + VisRTX. Might also do OSPRay and ProRender in the future.
Opening this issue in case you consider adding it to the documentation.
anariInfo -l helide
shows:
ANARI_SAMPLER transform:
* name ANARI_STRING
* inAttribute ANARI_STRING
* outTransform ANARI_FLOAT32_MAT4
* outOffset ANARI_FLOAT32_MAT4
This should be ANARI_FLOAT32_VEC4
for parameter outOffset
.
Compiling on macOS fails, when building only the GL viewer but not the GLES viewer.
This can be reproduced with a fresh checkout of the recent main
branch (commit f5ae12a) and configuring with:
cmake .. -DBUILD_VIEWER=ON -DBUILD_GLES_VIEWER=OFF
On make
, the compiler produces the following error message:

git-bisect
suggests that the regression was introduced by this commit: 6991cbf
Now user can't use glm matrix or float[16] as ANARI_FLOAT32_MAT4
type parameter. This case produces compilation error.
Looks like there's a missed ANARI_TYPEFOR_SPECIALIZATION for glm vectors and float arrays
Please make it possible to build the package in cases where no internet access is available. Now one has to copy all the .zip files. Also the pybind11 cloning is not possible.
How can I replace the fetch with a local copy?
THanks
Hi @jeffamstutz and @szellmann,
It may be useful to mention somewhere in the README that the example device
is based on OpenMP and as such early adopters should expect hardware optimized ANARI implementations will be provided by the corresponding vendor.
What do you think?
I am using Helide to render a sub-set of spheres. I've set the geometry's primitive.index
parameter to an ARRAY1D
of UINT32
. Positions and radii turn out correctly (they are obtained from indexing into vertex.position
and vertex.radius
) but not the spheres' colors. Their colors seem to be taken from the vertex.color
array without indexing.
The ANARI spec claims:
Each element of
primitive.index
defines one sphere, indexing into thevertex.*
arrays.
I am wondering whether I am observing a limitation (or bug) of the helide renderer or doing something wrong on the application side.
Hello. I found some some issues in ANARI test scenes:
In textured_cube.cpp, line 99, there's an incorrect subtype name ("texture2d", but correct name in documentation is a "image2D")
In random_spheres.cpp there's no release of surface. In line 49 anari:setParameter
is used instead of anari:setAndReleaseParameter
. Destructor of surface won't be called because surface have one reference.
In file_obj.cpp there's a undocumented parameter using ("vertex.texcoord") (line 139)
Hi,
I'd like to learn more about developing back end for ANARI with a specific interest in targeting offline CPU renderers.
I have built ANARI and toy around with the viewer.
My main development environment will be Ubuntu.
What example code should I start focusing on ? I have watched the OSPray back end development video from the ANARI Webinar 2022
Cheers
#16 added support for only including the glm dependency when BUILD_TESTING is on, but I believe it also needs to be enabled when BUILD_EXAMPLES is on.
I believe that in external/CMakeLists.txt
then the if statement for whether to download glm should read:
if (BUILD_TESTING OR BUILD_EXAMPLES)
I've tested this by verifying that the following succeeds:
$ cmake -DBUILD_TESTING:BOOL=ON -DBUILD_EXAMPLES:BOOL=ON
The following fails:
$ cmake -DBUILD_TESTING:BOOL=OFF -DBUILD_EXAMPLES:BOOL=ON
And that command succeeds after changing external/CMakeLists.txt
:
-if (BUILD_TESTING)
+if (BUILD_TESTING OR BUILD_EXAMPLES)
There seem to be two syntax errors in the file "herder_gen/anari_core_objects_1_0.json".
In my editor, the commas in lines 829 and 833 are displayed as incorrect.
anari::newArray
contains defaulted arguments that can cause ambiguity between overloads when used. The best remedy is to simply add 1/2/3D suffixes to each collection of functions.
In cornell box scene (cornell_box.cpp) there's a possible mistake. There's a check of ANARI_KHR_DEVICE_SYNCHRONIZATION feature (line 275), but it looks like that it should check ANARI_KHR_AREA_LIGHTS
Comparing ANARIDataType for equality used to work in c++17 but leads to compiler errors in c++20 using MSVC. This can be observed in the following code example:
#include "anari_enums.h"
bool isFloat(ANARIDataType anariDataType)
{
bool isFloat = anariDataType == ANARI_FLOAT32;
return isFloat
}
While this compiles fine using c++17 but gives the following errors in c++20 (shortend):
[build] ~\AnariDevice.cpp(171): error C2666: 'ANARIDataType::operator ==': overloaded functions have similar conversions
[build] ~\include\anari\frontend/anari_enums.h(14): note: could be 'bool ANARIDataType::operator ==(int) noexcept const'

...
This issue can solved in multiple ways:
ANARIDataType
to an int
compilation works.
bool isFloat(ANARIDataType anariDataType)
{
bool isFloat = (int)anariDataType == ANARI_FLOAT32;
return isFloat
}
struct ANARIDataType
constexpr bool operator==(ANARIDataType v) const noexcept { return v == value; }
!=
operator for int
to struct ANARIDataType
constexpr bool operator!=(int v) const noexcept { return v != value; }
So the issue can be solved complety client side, however, i thought you might want to know about the issue and maybe consider a library side fix as well.
