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. <p> Compressed geometry may be passed to this CompressedGeometryData 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. <p> <ul> <li> <b>By Copying:</b> In by-copy mode, the CompressedGeometryData constructor copies the buffer of compressed geometry data into this CompressedGeometryData object. This is appropriate for many applications, and allows Java 3D to verify the data once and then not worry about it again. </li> <li><b>By Reference:</b> In by-reference mode, the compressed geometry data is accessed by reference, directly from the user's array. To use this feature, you need to construct a CompressedGeometryData object with the <code>byReference</code> flag set to <code>true</code>. In this mode, a reference to the input data is saved, but the data itself is not necessarily copied. Note that the compressed geometry header is still copied into this compressed geometry object. Data referenced by a CompressedGeometryData object must not be modified after the CompressedGeometryData object is constructed. Applications must exercise care not to violate this rule. If any referenced compressed geometry data is modified after construction, the results are undefined. </li> </ul><P><P><DL><DT><B>Since:</B></DT> <DD>Java 3D 1.5</DD></DL><HR><P><!-- ======== NESTED
