Sure that's right but on the other hand you would gain full access on display lists, vertex, buffers, etc. And coding a rudimentary vector-math package which would fit most of the things one would need would propably just take a day (or there are already alot available on the internet). > Summing up, Java3D's pure immediate mode is even a great benefit for > developers. Hmm someone who's only focused using on pure intermediate mode is throwing around 80% of Java3D away IMHO. Ok besides he doesn't have to think that much about state changes of course (which is a benefit yes :) ). I've to say to my shame that a lot of my progs mostly use mixed-mode. Which is still a big problem with Java3D if you rely a lot on multi-pass-rendering or a special sequence rendering order (I know there is an ordered group node) it's hard not to come attracted to mixed-mode/pure-mode. > >Yes full (and I really mean full) OpenGL 1.3 support.

Well I don't know maybe because some of them aren't supported by DX as I'm not a DX-Guru I really can't tell though.
