Re: [JAVA2D] 2d api w/ OGL : I VOTE FOR THAT, and you Bich Thuy?

Hi Paul,

I also think that it would be great to have 2D and 3D homogeneous. I don't
know if using the Java3D API for the 2D is the best solution. I've just
heard, by several SUN sources, that they were trying to mix 2D and 3D. Does
it means that we will have one API replacing the 2D and the 3D APIs ? How
can the two different projects converge together if they have begun their
work with different concepts ?
I'm also worried about the 2D and 3D perfomances, but as SUN people seem to
work on it, my requests concern more the 2D/3D integration and overlapping.
I need to display 2D and 3D worlds, so will it be possible in future APIs to
render 2D animation overlapped on a 3D area ?

Thanks,

Bich-Thuy
