X3D Example Archives: Basic, Experimental Binary Compression

Eight.x3d mesh model used for compression tests

Experimental Binary Compression algorithm models demonstrate the potential of geometric compression techniques.

These developmental examples illustrate how geometric compression based on text-based ASCII encodings might be integrated into X3D scenes via Prototype nodes that encapsulate Script processing. The file-size reduction technique Coding Polygon Meshes as Compressable ASCII by Martin Isenburg and Jack Snoeyink is documented in award-winning papers presented at the Web3D 2002 and 2003 Symposia. A Shout3D implementation demonstration is also available.

Further work on the X3D Compressed Binary Encoding (CBE) can be found at X3D Binary Compression Capabilities and Plans wiki page.
