glSampleMaski — set the value of a sub-word of the sample mask
void glSampleMaski( | GLuint maskNumber, |
GLbitfield mask); |
maskNumberSpecifies which 32-bit sub-word of the sample mask to update.
maskSpecifies the new value of the mask sub-word.
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.
glSampleMaski is available only if the GL version is 3.2 or greater, or if the ARB_texture_multisample extension is supported.
GL_INVALID_VALUE is generated if maskIndex is greater than or equal to the value of GL_MAX_SAMPLE_MASK_WORDS.
