Cheers Justin, Tina...
What I'm doing involves a Java program (applet, for preference) controlling
a bunch of 3D figures as per a stream coming in - in its current
incarnation, the figures are just VRML boxes but ideally, in the end, it
would be nice if they look at least a bit like humans - with walking,
running and kicking animations... doesn't need to be anything too fancy.
I originally decided to go with VRML because in principle at least it
should be easier than a lower-level language to use for humanoid animation.
My final deadline for this project is mid-September, so I have two months
to completely finish it - but that includes a certain amount of writing
about it, so it would be good to get most of the technical work out of the
way a while before then.
Do you think it's likely that the Xj3D work will resolve all (or most) of
the problems associated with the EAI? That is - will it work properly with
a Java2 VM? Will it be faster than what we have now? Will it stop
crashing Netscape all the time?
Right now I'm thinking Java3D is probably my best bet... but I'm still a
bit worried that it might not really be that much faster than what I'm
getting with Cortona (it's hard to find like to compare with like) - and it
might be a bit on the hard side to do anything humanoid. Still, I think
it's within my power...
Thanks again for your help
