- A platform independent integer format in one byte size increments
depending on number of bits required. (intrinsic compression)
- A platform independent floating point format in one byte increments
depending on the exponent bits and precision required. (intrinsic compression)
- A platform independent code and behavior description format deigned
for effective run time efficiency 0 to 20% loss over native code.
- A powerful binary interpreter for the algorythmic description of
"generated" geometries and rule based objects, as well as interactive
conditional processing with the server. An ideal basis for a 3-D "PostSculpt".
- A deliberately open ended design intended to be a seed for further
It of course does not provide an architecture for a 3D database or other
"API" features other than those required to install another API, but,
support of such an architecture is it's main design purpose.
