Are you using an Intel driver/card? I've found similar problems on shaders that use tha second TU, especially with texture coordinates...

...sound easy... :p

Thank you.

Is there any code example I can use?

Hi, is it possible to implement cube shadow mapping in opengl (especially with GLSL).

I've found examples with DirectX but not with OpenGL.

Thank you.

...of course it is only a Gf 6200 ;)

Please can you explain more? I've no chance to read deep values with "GL_NV_multisample_filter_hint" on? Or there is a trick I can use ?

Thank you

I've discovered that the problem is present only if I use the extension "GL_NV_multisample_filter_hint", such as:

glHint(GL_MULTISAMPLE_FILTER_HINT_NV,GL_NICEST);

or

Hi, I'm trying to write a vertex shader that emulates the fixed function pipeline but using phong lighting.

The problem is in the code that computes the "Spot Attenuation". I use an ATI 9600 card...

Hi everybody, I've an ATI 9600 card with the last drivers (7.10) and I've tried to use the program "3DLabs GLSL ShaderGen".

It seams that only one light is working, or better, all the lights,...

I'm drawing in the main frame buffer and I have a 7900GT card with one of the latest driver. Don't know now (I'm at work).

Hi, With an NVidia card I'm not able to read the depth value of a fragment with multisample activated. With a ATI card seems to work.

I use the glReadPixels API with GL_DEPTH_COMPONENT and...

I'm using the ATI 9600 GT card with GLSL. I've the Catalyst 7.9 drivers on it.

It seams that only one light is available via gl_LightSource[] struct.

If I use gl_LightSource[1] or...

What are the language differences between the OpenGL Shading Language 1.00 and 1.10?

Are there unsupported commands? Syntax differences? ...

Thank you
