gl_SampleMaskIn — contains the computed sample coverage mask for the current fragment
in int gl_SampleMaskIn[];
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.
