Hi ckw,<br>
Kepler uses Ptolemy II as its computational engine.<br>
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.<br>
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.<br>
<br>
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.<br>

Just like to ask around if there is a good computational geometry
library to be use with kepler ? A good library that can perform
geometry operation such as intersection, difference, union both in
2d and 3d ? Thanks <br>
