Class GeometryCompressor

java.lang.Object
  com.sun.j3d.utils.geometry.compression.GeometryCompressor

public class GeometryCompressor
extends java.lang.Object

A GeometryCompressor takes a stream of geometric elements and quantization parameters (the CompressionStream object) and compresses it into a stream of commands as defined by appendix B of the Java 3D specification. The resulting data may be output in the form of a CompressedGeometryData node component or appended to a CompressedGeometryFile.

Since:

Java 3D 1.5

Method Summary

CompressedGeometryData	compress(CompressionStream stream) Compress a stream into a CompressedGeometryData node component.

Method Detail

compress

public CompressedGeometryData compress(CompressionStream stream)

Compress a stream into a CompressedGeometryData node component.

Parameters:

stream - CompressionStream containing the geometry to be compressed

Returns:

a CompressedGeometryData node component

compress

public void compress(CompressionStream stream,
                     CompressedGeometryFile f)
              throws java.io.IOException

Compress a stream and append the output to a CompressedGeometryFile. The resource remains open for subsequent updates; its close() method must be called to create a valid compressed geometry resource file.

Parameters:

stream - CompressionStream containing the geometry to be compressed

f - a currently open CompressedGeometryFile with write access

Throws:

java.io.IOException - if write fails
