Class RayContext

java.lang.Object
  de.grogra.ray.util.RayContext

public class RayContext
extends java.lang.Object

This class is needed for a correct intersection computation. Because the lack of precision in floating point operations there must be remembered some context information. Additionally it is used to optimize the intersection processing by knowing the former computation context.
