This sample illustrates the use of curvature. The project consists in creating a mountain range and then applying a smoothing effect locally to places where the slope does not vary, i.e. where the curvature is zero. The result is a mountain range that seems more eroded without having to use a more realistic, but costly in performance, erosion simulation.

Several groups of nodes are used in this project to help you understand better the different effects of the procedural process. See Grouping nodes for details on how to create groups of nodes.
