BaryCoordNoPerspKHR(3)

Name

BaryCoordNoPerspKHR - Barycentric coordinates of a fragment in screen-space

Description

BaryCoordNoPerspKHR

The BaryCoordNoPerspKHR 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 linear interpolation.

Valid Usage

  • VUID-BaryCoordNoPerspKHR-BaryCoordNoPerspKHR-04160
    The BaryCoordNoPerspKHR decoration must be used only within the Fragment Execution Model

  • VUID-BaryCoordNoPerspKHR-BaryCoordNoPerspKHR-04161
    The variable decorated with BaryCoordNoPerspKHR must be declared using the Input Storage Class

  • VUID-BaryCoordNoPerspKHR-BaryCoordNoPerspKHR-04162
    The variable decorated with BaryCoordNoPerspKHR must be declared as a three-component vector of 32-bit floating-point values
