A couple of comments:
1) You should be successful with Java3D but you will need to carefully
optimize performance.
2) Java2D would be a disaster as it is very slow compared to Java3D.
I will admit the possibility that some very clever programming MIGHT
give you adequate performance but I will say that I have tried and
others have tried and failed. You could do raster graphics for this
problem in C/C++ but Java just doesn;t seem to hack it.
3) You will need to have an adequate graphics card (GeForce or similar).
4) Because your scenegraph will be dynamic this will be a CPU hog -
assume that you will need a fast CPU.
