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 number of color samples supported by the implementation.
