Description

BaryCoordSmoothAMD

The BaryCoordSmoothAMD 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 perspective interpolation at the fragment’s center. The K coordinate of the barycentric coordinates can be derived given the identity I + J + K = 1.0.

Valid Usage

  • VUID-BaryCoordSmoothAMD-BaryCoordSmoothAMD-04172
    The BaryCoordSmoothAMD decoration must be used only within the Fragment Execution Model

  • VUID-BaryCoordSmoothAMD-BaryCoordSmoothAMD-04173
    The variable decorated with BaryCoordSmoothAMD must be declared using the Input Storage Class

  • VUID-BaryCoordSmoothAMD-BaryCoordSmoothAMD-04174
    The variable decorated with BaryCoordSmoothAMD must be declared as a two-component vector of 32-bit floating-point values
