GLSAMPLEMASKI(3G) [FIXME: manual] GLSAMPLEMASKI(3G)
NAME
glSampleMaski - set the value of a sub-word of the sample mask
C SPECIFICATION
void glSampleMaski(GLuint maskNumber, GLbitfield mask);
PARAMETERS
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.
