Hi!
We have tested the Java3d-CollisionEngine in a project some months ago.
We needed exact collsion detection (a bounding box was to unprecise). But
the build-in Java3d collision was far to slow. So we switched to vcollide
(written in c) and jni ( :( porting to other platforms sucks ).
My question: Has someone else experience with the java3d collision engine?
Is the detection fast enough (if yes, what a machine are you using)?
We'd like to have our project implemented in pure Java/Java3d. (Have i
mentioned, that porting to other platforms sucks? :) )
thx in advance
