BaryCoordKHR(3)

Name

BaryCoordKHR - Barycentric coordinates of a fragment

Description

BaryCoordKHR

The BaryCoordKHR decoration can be used to decorate a fragment shader input variable. This variable will contain a three-component floating-point vector with barycentric weights that indicate the location of the fragment relative to the screen-space locations of vertices of its primitive, obtained using perspective interpolation.

Valid Usage

  • VUID-BaryCoordKHR-BaryCoordKHR-04154
    The BaryCoordKHR decoration must be used only within the Fragment Execution Model

  • VUID-BaryCoordKHR-BaryCoordKHR-04155
    The variable decorated with BaryCoordKHR must be declared using the Input Storage Class

  • VUID-BaryCoordKHR-BaryCoordKHR-04156
    The variable decorated with BaryCoordKHR must be declared as a three-component vector of 32-bit floating-point values
