[kepler-users] 3d geometry library

[Christopher Brooks]

Hi ckw,
Kepler uses Ptolemy II as its computational engine.
Ptolemy II has an interface to Java 3D called the gr model of 
computation, which is more of a 3D rendering facility than a library for 
geometry, but it might have what you need.
Instantiating Ptolemy II Java 3D actors from within Kepler could be 
tricky, probably because ptolemy/domains/gr is excluded from the build.  
So, it would be best if you reviewed Java 3D and determined if it meets 
your needs, then downloaded Ptolemy II 8.0 and tried to use the gr model 
of computation.  If Java 3D meets your needs, then you could build 
Kepler from source and then we could work on getting the Java 3D actors 
to work within Kepler.

The Ptolemy II development tree includes a start on an interface to 
Jogl, the Java OpenGL interface, but that code never worked, will not 
ship in a release as it stands and could be removed at any point in time.
