public class CompressedGeometry
extends Geometry

The compressed geometry object is used to store geometry in a compressed format. Using compressed geometry may increase the speed objects can be sent over the network. Note that the geometry will be decompressed in memory, so the application will not see any memory savings.

Compressed geometry may be passed to this CompressedGeometry object in one of two ways: by copying the data into this object using the existing constructor, or by passing a reference to the data.

Constructor Detail

CompressedGeometry

public CompressedGeometry(CompressedGeometryHeader hdr,
                          byte[] compressedGeometry)
Deprecated. 
Creates a new CompressedGeometry NodeComponent by copying the specified compressed geometry data into this object. If the version number of compressed geometry, as specified by the CompressedGeometryHeader, is incompatible with the supported version of compressed geometry in the current version of Java 3D, then the compressed geometry object will not be rendered.

Parameters:
hdr - the compressed geometry header. This is copied into the CompressedGeometry NodeComponent.
compressedGeometry - the compressed geometry data. The geometry must conform to the format described in Appendix B of the Java 3D API Specification.
Throws:
java.lang.IllegalArgumentException - if a problem is detected with the header
See Also:
CompressedGeometryHeader, Canvas3D.queryProperties()

CompressedGeometry

public CompressedGeometry(CompressedGeometryHeader hdr,
                          byte[] compressedGeometry,
                          boolean byReference)
Deprecated. 
Creates a new CompressedGeometry NodeComponent. The specified compressed geometry data is either copied into this object or is accessed by reference. If the version number of compressed geometry, as specified by the CompressedGeometryHeader, is incompatible with the supported version of compressed geometry in the current version of Java 3D, the compressed geometry object will not be rendered.

Parameters:
hdr - the compressed geometry header. This is copied into the CompressedGeometry NodeComponent.
compressedGeometry - the compressed geometry data. The geometry must conform to the format described in Appendix B of the Java 3D API Specification.
byReference - a flag that indicates whether the data is copied into this compressed geometry object or is accessed by reference.
Throws:
java.lang.IllegalArgumentException - if a problem is detected with the header
Since:
Java 3D 1.2

getByteCount

public int getByteCount()
Deprecated. 
Returns the size, in bytes, of the compressed geometry buffer. The size of the compressed geometry header is not included.

getCompressedGeometryHeader

public void getCompressedGeometryHeader(CompressedGeometryHeader hdr)
Deprecated. 
Copies the compressed geometry header from the CompressedGeometry NodeComponent into the passed in parameter.

Parameters:
