public class Tesselator
extends Object

The Tesselator class is a GLUtessellator utility wrapper. Its main purpose is the creation of a RenderableQualityModel out of a GeometryQualityModel by triangulating (tesselating) all it's SimpleAccessGeometry.

Constructor Summary

Tesselator(boolean useDirectBuffers)
Create a tesselator which triangulates all SimpleAccessGeometry of a GeometryQualityModel.

Method Summary

RenderableQualityModel	createRenderableQM(String objectID, GeometryQualityModel originalObject) Create a renderable quality model from the given 'original' geometry model, by tesselating (triangulating) its polygons.
RenderableGeometry	tesselateGeometry(SimpleAccessGeometry originalGeometry) Create a renderable geometry from the given SimpleAccessGeometry by tesselating it.

Constructor Detail

Tesselator

public Tesselator(boolean useDirectBuffers)

Create a tesselator which triangulates all SimpleAccessGeometry of a GeometryQualityModel.

Parameters:

useDirectBuffers - to use direct buffers instead of heap buffers.

Method Detail

createRenderableQM

public RenderableQualityModel createRenderableQM(String objectID,
                                                 GeometryQualityModel originalObject)

Create a renderable quality model from the given 'original' geometry model, by tesselating (triangulating) its polygons.

Parameters:

objectID - identifying the given quality model, if an error occurs. May be null

originalObject - containing polygons

Returns:

the renderable object.

tesselateGeometry

public final RenderableGeometry tesselateGeometry(SimpleAccessGeometry originalGeometry)

Create a renderable geometry from the given SimpleAccessGeometry by tesselating it.

Parameters:

originalGeometry - may not be null.

Returns:

the RenderableGeometry or null if the given geometry could not be triangulated.
