SPIR-V Built-In
BaryCoordNoPerspKHR
Barycentric coordinates of a fragment in screen-space
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
