Class DEMDatasetGenerator

java.lang.Object
  org.deegree.tools.rendering.dem.builder.DEMDatasetGenerator

@Tool(value="Generates DEM multiresolution datasets from rasters, suitable for the WPVS.")
public class DEMDatasetGenerator
extends Object

Tool for generating the binary files for MultiresolutionMesh instances (MRIndex- and PatchData-BLOBs) from regular heightfields.

The input heightfield file must contain the raw height information as a sequence of height values (heixels). Contained in a raster.

Initially, the domain is divided into two right triangles. These are the root fragments of the multiresolution hierarchy. Smaller fragments (with more detail) are generated by recursively bisecting the triangles.
