Raymondo: You''re right it WAS a innocent question, that is until he said that any advice other then a direct answer to his questions is waste of time. The first AP was obviously pointing out that these weren''t relevant questions for his project at this time. Were not trying to put down his vision, just help him get there.

As far as my advice goes, its pretty much the same as all the above that dealt with needing to have of an idea of what features the engine will have.

Perhaps you should take a look at some 3D engines out there and tell us if one of them aproximates your vision. Then we might be able to give you a more specific answer, even if you plan on writing your own.
