Hi all

It seems I have similar problem. In my shader, first texture stage is reserved for base map, second for normal map and finally third one for shadow map. Validation fails with already...

Hi All

1) How to query or enumerate a list of supported internal texture formats ??

2) Is there anywhere in net reference manual for ogl 1.5 (better than ogl 1.5 spec from opengl.org)??

we missunderstood - I have color in d3d format which means ARGB and I want to use this color for Opengl vertices - but opengl uses RGBA so :

I have color in format

Helo everyone

I'm using direct3d vertex format where color is 32 bits integer (ARGB). I want to redirect vertices stream to OGL renderer but I have problem with color - is it possible to use ARGB...

Thanks. I watched this post and that is the effect I desire, but author uses NV, ARB and ATI extensions - is there any simplification ??

hello

Here is the problem: I have two textures:

texture 1 (RGB) and texture 2 (RGBA). I want to mix these textures ( GL_ARB_multitexture ) in particular way.

1) I want to obtain effect where...

Hello

I have just read ARB_fragment_program specification and I have noticed that author using GLslang samples - where can I find some usefull info about GLSlang (compilers, tutorials, examples)??...

Hello

I just read glslang specification and I'm wondering where can I find some demos of glslang codes and any other usefull info about it.

Thank you!

Ok-thanks, but is there any tutorial with procedural textures and ARB_fragment_program?

best regards

Hello

I'm looking for some tutorial with procedural texturing supported by ARB_vertex_program or NV_vertex_program. Thanks.

Hello again

These solutions don't seem to be effective enough. Is there any algorithm for correction of reverced faces??

best regards
Marcin

there are two solutions for your problem:

1.duplicate your vertices so, that every triangle has it's unique vertex. no shared vertices at all.(as i said ineffective)

2. render your object in...

Hello everybody

I have the following problem: I'm drawing a simple cube. All lighting setings are appropriate (shading is corect) but when I enable texturing shade disappears!! Does anyone know...

thanks

Thanks for answer. I have to use glTexImage3D routine which is available since openGL 1.2 !! I have watched my Indygo extensions but there was nothing like texture 3D.
