Curvature (Filter Node)

Description

Performs a simple, harsh single-pass curvature conversion to input Normalmap. The resulting map has white tints for convex areas and black tints for concave. Curvature will always produce pixel-thin lines and sharp transitions.

This node is useful for some quick highlighting or darkening of certain edges. It is limited in comparison to Curvature Smooth (which produces higher quality results) and Curvature Sobel (which has more options).
