Class SpatialSelection

java.lang.Object
  org.deegree.rendering.r3d.multiresolution.SpatialSelection

public class SpatialSelection
extends Object

Implementation of spatial selection algorithm for MultiresolutionMesh.

This is a variant of the SelectiveRefinement algorithm that only extracts a region of an LOD that lies inside a certain region of interest (ROI). Mesh fragments outside the roi are clipped.
