This error results when the GeometryArray that the decompressor was trying to output was created with a format that didn't specify colors, yet what appeared to be a color was nonetheless encountered in the compressed data. This could be a bug either in the Java 3D decompressor or in your compressor implementation; it's not possible to tell with the given information. If your compressor was derived from the ObjectFileCompressor example code, then it's possible that you may be getting default colors provided by the ObjectFile superclass which you're not accounting for in creating the compressed data. Try using the CompressedGeometryFile class to write out a .cg file of one of your smaller models and send it to me, and I'll take a look at it. We hope to have some compression verification tools available in a future release of Java 3D. > Also during compression of huge models (20MB data) I sometimes get error > OutOfMemmory > I am working on a Sun Ultra 60/1GB RAM I haven't tried compressing anything that large myself yet. I'll try a few larger models with the Java 3D compressor and see what the memory consumption looks like. Try using the -Xmx switch to the Java interpreter to increase the size of the virtual machine if you're not doing that already. We're actively maintaining and improving the Java 3D compressed geometry utilities. If you can verify memory leaks, performance problems, or other bugs in the Java 3D compressor, let us know and we'll try to fix them. -- Mark Hood =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
