Curvature

The Curvature map is an important ingredient of the Advanced Terrain Shader’s ‘Terrain’ layer and is a good way to color rocks and ridges.

Curvature is also available in the Terrain Operator Shader, the Grid Preview tab, and the Grid Monitor, as well as a dedicated layer type in the Advanced Terrain Shader.

The full raw Curvature map.

Bumps

A derivative of the Curvature map.

Only positive curvature is included in this map.

Very suitable to isolate bumps and ridges, e.g. rocks.

Dents

Another derivative of the Curvature map.

Only negative curvature is included in this map.

Very suitable to isolate dents and depressions, rifts and cracks.
