NAME¶
gl_SampleMaskIn - contains the computed sample coverage mask for the current
fragment
DECLARATION¶
in int gl_SampleMaskIn[] ;.SH "DESCRIPTION"
gl_SampleMaskIn is a fragment language that indicates the set of samples
covered by the primitive generating the fragment during multisample
rasterization. It has a sample bit set if and only if the sample is considered
covered for this fragment shader invocation. Bit
B of mask
gl_SampleMask[M] corresponds to sample 32 *
M +
B. The
array has
ceil(
s / 32) elements where
s is the maximum
