Class BumpMappingFactory

java.lang.Object
  org.xith3d.effects.bumpmapping.BumpMappingFactory

Direct Known Subclasses:

AssemblyBumpMappingFactory, GLSLBumpMappingFactory

public abstract class BumpMappingFactory
extends java.lang.Object

The BumpmappingFactory is capable of preparing a Shape3D for Bumpmapping. the underlying methods to calculate tangets/bitangets and to load the appropriate shaders are also public to use them for different perposes.

prepareForBumpMapping

public abstract void prepareForBumpMapping(Shape3D shape,
                                           Texture normalMapTex)
                                    throws java.io.IOException
