Well, almost 9 months after getting my Mac, no apps have impressed me as much as trueSpace and MoI on Windows, maybe i should check out cinemia4D et al.

On the other hand, with the advent of JavaFX how hard can it be to write a 3D app that works how i want it to?
Yeah you guessed, really hard, but at least in theory the UI side of things should be easier (then with Java) thanks to JavaFX, just the 3D coding is going to be a nightmare.
Not sure OpenGL helps here, for display and render, for sure, but for manipulation.....Hmmmm

Perhaps another challenge i will get bored of after a few days of getting nowhere fast!!
