Class GeometryUtility

java.lang.Object

de.jreality.geometry.GeometryUtility

public class GeometryUtility
extends Object

Static methods for various geometric operations.

There are a few basic categories:

• static fields for specific geometry attributes,
• methods for calculating normal vectors for IndexedFaceSet instances,
• methods for calculating bounding boxes for PointSet instances,
• analogous methods which traverse scene graphs, and
• methods for transforming the geometry in a scene graph in some way.
