X3D Example Archives: Basic, Experimental Binary Compression

Eight.x3d mesh model used for compression tests

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.
