glSampleMaski: set the value of a sub-word of the sample mask
Function Definition
void glSampleMaski(GLuint maskNumber, GLbitfield mask);
- maskNumber
- Specifies which 32-bit sub-word of the sample mask to update.
- mask
- Specifies the new value of the mask sub-word.
Description
glSampleMaski sets one 32-bit sub-word of the multi-word sample mask, GL_SAMPLE_MASK_VALUE.
maskIndex specifies which 32-bit sub-word of the sample mask to update, and mask specifies the new value to use for that sub-word. maskIndex must be less than the value of GL_MAX_SAMPLE_MASK_WORDS. Bit B of mask word M corresponds to sample 32 x M + B.
Notes
glSampleMaski is available only if the GL version is 3.2 or greater, or if the ARB_texture_multisample extension is supported.
Errors
GL_INVALID_VALUE is generated if maskIndex is greater than or equal to the value of GL_MAX_SAMPLE_MASK_WORDS.
