[kepler-users] 3d geometry library

[Derik Barseghian]

You could also use one of the actors that interfaces with external systems, e.g. the Matlab, or R actor (e.g. with the geometry package).

> 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.
