.SH "NAME"
gl_SampleMaskIn \- contains the computed sample coverage mask for the current fragment
.SH "DECLARATION"
in\ \&int\ \&gl_SampleMaskIn[]\ \&;.SH "DESCRIPTION"
.PP
\fIgl_SampleMaskIn\fR
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
\fIB\fR
of mask
\fIgl_SampleMask[M]\fR
corresponds to sample 32 *
\fIM\fR
+
\fIB\fR\&. The array has
\fBceil\fR(\fIs\fR
/ 32) elements where
\fIs\fR
is the maximum number of color samples supported by the implementation\&.
