Description

BaryCoordNoPerspSampleAMD

The BaryCoordNoPerspSampleAMD decoration can be used to decorate a fragment shader input variable. This variable will contain the (I,J) pair of the barycentric coordinates corresponding to the fragment evaluated using linear interpolation at each covered sample. The K coordinate of the barycentric coordinates can be derived given the identity I + J + K = 1.0.

Valid Usage

  • VUID-BaryCoordNoPerspSampleAMD-BaryCoordNoPerspSampleAMD-04166
    The BaryCoordNoPerspSampleAMD decoration must be used only within the Fragment Execution Model

  • VUID-BaryCoordNoPerspSampleAMD-BaryCoordNoPerspSampleAMD-04167
    The variable decorated with BaryCoordNoPerspSampleAMD must be declared using the Input Storage Class

  • VUID-BaryCoordNoPerspSampleAMD-BaryCoordNoPerspSampleAMD-04168
    The variable decorated with BaryCoordNoPerspSampleAMD must be declared as a two-component vector of 32-bit floating-point values
