I see a lot of questions around about octtrees and I figure I''ll put that into my current engine. I''m hoping to make it more generalized (indoor, outdoor, app viewer) and so octrees seem like a good general solution. Now the questions: 1. Let''s say that I have an indoor level that is being partitioned by the octree, should I split the polygons or just maintain what nodes a polygon are in and make sure not to draw twice? What are the bonuses/drawbacks of each? I hear people talking about both methods so I had to ask.... 2. Which spelling is correct, octree or octtree? Why? 3. Any good links to an octree tutorial?

I think you''ll want to split your polys. The added polys will not cost more than checking for polys rendered once for every frame.

Never done it, so I may be wrong, but I think splitting will be easiest and fastest.

^^^ I agree - but I''m no expert.
