Undo barycentric interpolation

Trending 1 year ago

How do I undo nan interpolation of vertex attributes? I'm utilizing unity shader chart which doesn't support nointerpolation. I presume I request to shop 3 float3 pinch 1 constituent of each float3 being 1 and nan remainder 0, this will springiness nan barycentric coordinate. But I don't cognize really to really usage them to undo nan interpolation.
