Left Toolbar > Normal Nodes > Normal Curvature
The Normal Curvature node finds the average curvature between the normals around each pixel.
On the left toolbar choose Normal Nodes > Normal Curvature. >
Drag the Normal Curvature icon into the Node Graph.
Connect a Normal image to the input socket in the Normal Curvature node.
Connect the Output: Curvature, Convex or Concave.
A Normal Image.
A monochromatic image where 50% gray represents flat areas, white represents convex areas, and black represents concave areas.
Convex A monochromatic image where black represents flat areas and white represents convex areas.
Concave A monochromatic image where black represents flat areas and white represents concave areas.
Radius Defines a circular area around each pixel that is measured for curvature.
