I need to access a bunch of constant values in my GLSL geometry shader. I tried it this way: const int lookup[HUGE_NUMBER] = 开发者_Python百科int[HUGE_NUMBER](1,32,...)
does HLSL have predefined variables for common matrices like GLSL has? i am looking for gl_Proje开发者_JAVA技巧ctionMatrix and gl_ModelViewMatrix respectively?
I don\'t wish to bombard this post with code. I\'ve got a main file, fragment shader and a vertex shader file.
Talking about bump mapping, specular highlight and these kind of things in OpenGL Shading Language (GLSL)

I\'m trying to implement texture projection based directly on this example at oZone3d.My environment is OpenGL ES 2.0 on Android 2.2.
What would be the best way to send my bit flag to the fragment shader in order to be able to if() against it?
I\'m very new to GLSL, but I\'m trying to write convolution kernel with in a fragment shader for image processing.I was able to do this just fine when my kernel was small (3x3) using a constant matrix
specs: Radeon 3870HD w/ openGL 3.3 & GLSL 1.5 I am rendering data through computational shader. Because of dependenci开发者_开发技巧es I had to put all my data to uniform textures and nothing lef
I need to setup a GLSL fragment shader to change the color of a fragment other than the one currently being processed. Since that may not seem desirable, I\'ll provide a very brief context.
