This module contains facets and their corresponding providers which available as plugins that provide extra information about the world surface.
Contains the surface normal data for each point in a world.
Contains the surface steepness (which is the angle in radians between the surface normal and the vertical) data for each point in a world.
Produces a SurfaceNormalFacet with the surface normals for a world obtained from its surface heights.
Produces a SurfaceSteepnessFacet with the surface steepness for a world obtained from its surface heights.
You can either directly add the providers to your world builder via addProvider or add all of them as plugins via addPlugins. The facets contain data as a 2D field of the surface points much like SurfaceHeightProvider and can be used in rasterizers.
For an example of how the facets can be used to generate worlds, take a look at the world generator and rasterizer under the examples subpackage. The example can be run by using the SurfaceFacets Example world generator after activating the module.
