Notes:
Chisel is an excellent tool for overall file optimization and geometry reduction.
Some problems are not amenable to automated tools and require a detailed understanding of the underlying processing of X3D browsers. It can be useful to bring in an expert if the problems seem intractable.
The optimization phase is iterated until the desired performance characteristics are achieved.
Once the optimization has been completed, the world needs to be packaged for delivery. Depending upon the delivery of the content (web, CD, stand-alone), the packaging can take different forms. Frequently all of the world files are compressed using gzip and everything is loaded into the correct distribution directories.
