Normal Curvature node

Left Toolbar > 3D icon 3D Nodes > Normal Curvature

The Normal Curvature node finds the average curvature between the normals around each pixel.

Mesh Distance Curvature

Mesh Distance Convex

Mesh Distance Concave

Procedure

To generate the Curvature image from a Normal image:

  1. On the left toolbar choose 3D Nodes > Normal Curvature. 3D icon > Normal Curvature icon

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

    Mesh Position node

  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.

Attributes Panel

Normal Curvature attributes

Position X Position X of the output image.

Position Y Position Y of the output image.

Size X Size X of the output image.

Size Y Size Y of the output image.

Radius Defines a circular area around each pixel that is measured for curvature.

Range Defines the maximum curvature and gives more contrast to the output image.
