Sat Nov 12 09:46:35 PST 2011
These tests verify that the following built-in shader input variables
are read-only:
For vertex shaders:
- gl_Color
- gl_SecondaryColor
- gl_Normal
- gl_Vertex
- gl_MultiTexCoord0
- gl_MultiTexCoord1
- gl_MultiTexCoord2
- gl_MultiTexCoord3
- gl_MultiTexCoord4
- gl_MultiTexCoord5
- gl_MultiTexCoord6
- gl_MultiTexCoord7
- gl_FogCoord
- gl_VertexID (a GLSL 1.30 feature)
For fragment shaders:
- gl_FragCoord
- gl_FrontFacing
- gl_Color
- gl_SecondaryColor
- gl_TexCoord
- gl_FogFragCoord
- gl_PointCoord
- gl_ClipDistance (a GLSL 1.30 feature)
