InvocationsPerPixelNV(3)

Name

InvocationsPerPixelNV - Number of fragment shader invocations for the current pixel

Description

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.

Valid Usage

  • VUID-InvocationsPerPixelNV-InvocationsPerPixelNV-04260
    The InvocationsPerPixelNV decoration must be used only within the Fragment Execution Model

  • VUID-InvocationsPerPixelNV-InvocationsPerPixelNV-04261
    The variable decorated with InvocationsPerPixelNV must be declared using the Input Storage Class

  • VUID-InvocationsPerPixelNV-InvocationsPerPixelNV-04262
    The variable decorated with InvocationsPerPixelNV must be declared as a scalar 32-bit integer value
