What steps will reproduce the problem?
1. Run configure script without LDFLAGS=-lm
2. Run make
What is the expected output? What do you see instead?
The library doesn't successfully build unless you pass LDFLAGS=-lm as an
argument to "./configure". libm isn't linked against by default, so you get
undefined references to things like pow().
What version of the product are you using? On what operating system?
20080909
Debian GNU/Linux

I had some little problems with the lib (2 RC1 - 20080909). It was mostly
conversions the compiler wanted to be explicit. I also included the same
kind of patch "pompei2" submitted (1999591).
So, here are the modified files.

What steps will reproduce the problem?
1.I have installed the lib3ds library
2.I have put a .3ds file in my working directory
3.the relevant code snippet is
lib3ds* model;
model= lib3ds_file_open("hand.3ds")
What is the expected output? What do you see instead?
Instead of loading the model the pointer always returns null although the
function is recognized by the IDE.
What version of the product are you using? On what operating system?
lib3ds 2.0 with codeblocks 10.05 on windows 7 x64
Please provide any additional information below.

In render_node() as is, glGetError() can return GL_INVALID_VALUE. This is
caused by the line
glMaterialf(GL_FRONT, GL_SHININESS, pow(2, 10.0*mat->shininess));
Change that to
glMaterialf(GL_FRONT, GL_SHININESS, min(128.,pow(2,
10.0*mat->shininess)));
to resolve the issue. I've seen mat->shininess be 10.0 in file,
GL_SHININESS should not be passed over 128.

Hello,
here some notes about 20080909 lib3ds version:
1. (main) (result: incorrect vertices positions calculation)
#define LIB3DS_EPSILON (1e-8)
// original define #define LIB3DS_EPSILON (1e-5)
1e-5 is too large value for the matrix calculation in the float range.
in case of 1e-5 use sometimes lib3ds_matrix_inv function fails,
because of return in this case:
if (fabs(determinat)<LIB3DS_EPSILON) {
return(0); /* Matrix is singular (zero determinant) */
(if you need I can send you a 3ds file which gives incorrect result)
2. (minor)
function lib3ds_vector_neg(float c[3]) does not have implementation in the
lib3ds_vector.c file.
3. (minor)
lib3ds_matrix_mult(float m[4][4], float a[4][4], float b[4][4]) {
float tmp[4][4]; // should be removed
int i, j, k;
float ab;
memcpy(tmp, a, 16 * sizeof(float)); // should be removed and 'a' matrix
should be used
for (j = 0; j < 4; j++) {
for (i = 0; i < 4; i++) {
ab = 0.0f;
for (k = 0; k < 4; k++) ab += tmp[k][i] * b[j][k];
m[j][i] = ab;
}
}
}

Hi,
I am confused about the license terms of lib3ds.
The COPYING file refers to the GPL.
The google code home page refers to LGPL.
Which of those two is the correct one?
Thx,

I got bored of the constant reports of “missing chunk 0xA08A” when reading
3ds-files. After a bit of research I discovered that this property is related
to the advanced transparency settings for the material in 3D studio. In this
case the falloff parameter. These controls affect the opacity falloff of a
transparent material. And the property chooses whether falloff is in or out.
See here for more information about Advanced Transparency:

Static linking is currently not supported! Defining LIB3DS_STATIC might solve
the problem (see lib3ds.h).

In the call to glTexCoord2f in 3dsplay.c, it looks to me like the texture
coordinates are switched. The V coordinate is sent as the U coordinate, and
the other way around. Changing it makes 3DS models with texturing look
good, while the default/current code makes texturing look funny.
Let me know if you need an example model to see it.

I find a bug in demo code "3dsplay.cpp"
in function
static void render_node(Lib3dsNode *node)
{
...
#ifdef USE_SDL
Player_texture *pt = NULL;
int tex_mode = 0;
#endif
if (mesh->faces[p].material > 0) {
mat = file->materials[mesh->faces[p].material];
}
...
}
I think "if (mesh->faces[p].material > 0) " should to "if
(mesh->faces[p].material >= 0) "
if use ">", it could not use first material in 3ds file.

I found a problem on big-endian systems, e.g. Sun
SPARC/Solaris, where the node tree for hierarchical models
is not being built correctly.
The problem is in lib3ds_file.c, kfdata_read. It passes the
address of a Lib3dsNode user_id to bsearch. user_id is an
unsigned int. But the bsearch comparison routine
compare_node_id2 is casting it to the address of an unsigned
short. This will work on little-endian systems (for
user_id<65535) but doesn't work on a big-endian system. When
the user_id value is accessed the top two (null) bytes are
being referenced.
The following simple patch fixes the problem.

Hello, currently there is no support for static linkage on Visual Studio (I
mean just including the lib3ds source files into your app/game project
file).
Kabey fixed this, here is the (simple) patch. Note that he did not add a
configuration to the visual studio project, but this could be easily done
by you.
Here is the patch for it, hope you enjoy:

I have exported a model from blender into 3ds max. The blender .3ds import
plugin manages to load the exported .3ds file with no problems, but lib3ds
seems to have problems, as it causes an assertion fail:
3dsplay: ../lib3ds_chunk.c:72: lib3ds_chunk_read_next: Assertion `c->cur ==
c->end' failed.
I'm using the current svn trunk code.
You can find an archive that contains both the .3ds and the .blend file
here:
http://arkana-fts.sourceforge.net/Archive.tar.gz
as The file is too big to be attached.

What steps will reproduce the problem?
1. Download the 3DS file http://www.baument.com/restore/Models/Faucet1.zip
available at http://www.baument.com/restore/archives.html
2. Read it with lib3ds
3. In smooth normals computation part of lib3ds_mesh_calculate_vertex_normals
function of lib3ds_mesh.c, this should lead to a few incorrect normals (I say
"should" because I got this result using a pseudo-translation of lib3ds in Java
3D).
What is the expected output? What do you see instead?
Getting default normals from lib3ds_vector_normalize when length is 0 isn't a
major issue, but it would be better to keep the default normal in that case
(i.e. the normal computed before smoothing operation). After line 222 of
lib3ds_mesh.c, I would suggest to add this test:
if (lib3ds_vector_length(n) == 0) {
lib3ds_vector_copy(n, fa[3*i+j].normal);
}
(with an additional lib3ds_vector_length_squared function, you could spare a
call to sqrt here)
What version of the product are you using?
I looked to source code of version 20080909

I am making a game in OpenGL in which I am using lib3ds to draw model. When I
run the game on a laptop which does not have graphics card or if it has, the
driver has not been activated from System->Administration->Hardware, then the
game works fine, everything loads pretty well. But when I activate the graphics
driver, The model does not load properly. The colour which was originally in
the model does not appear on the screen. Instead, all polygons are colored
white.
What is the expected output? What do you see instead?
Expected output is a screen with model loaded properly. Instead I see a
fluctuating window appearing and also the colors are not appearing properly.
What version of the product are you using? On what operating system?
2.0.0, on Ubuntu 10.04
Please provide any additional information below.
When I deactivate the graphics driver, the model loads perfectly fine and the
game runs fine.
The fluctuating output is attached.

Howdy,
I decided to take a look at 3dlib, but I'm having some problems compiling the
example code that comes along with the source.
I'm using codeblocks and i'm getting undefined references. I think it mighty be
a problem of linking.
I tried to add to the search directories (in linker) the /usr/include/lib3d
folder, but unsuccessful.
Can someone please give me a hint?
Thanks in advance.
