Procedure

To generate the Curvature image from a Normal image:

  1. On the left toolbar choose Normal Nodes > Normal Curvature. Normal icon > Normal Curvature icon

  2. Drag the Normal Curvature icon into the Node Graph.

  3. Connect a Normal image to the input socket in the Normal Curvature node.

  4. Connect the Output: Curvature, Convex or Concave.

Inputs

A Normal Image.

Outputs

Curvature
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.
