InvocationsPerPixelNV
InvocationsPerPixelNV
Decorating a variable with the InvocationsPerPixelNV
built-in
decoration will make that variable contain the maximum number of fragment
shader invocations per pixel, as derived from the effective shading rate for
the fragment.
If a primitive does not fully cover a pixel, the number of fragment shader
invocations for that pixel may be less than the value of
InvocationsPerPixelNV
.
If the shading rate indicates a fragment covering multiple pixels, then
InvocationsPerPixelNV
will be one.
