OT: Vertice magnitude


This isn’t openGL specific but more of a design issue. I’ve always created my models with vertices in the range of -2 to 2, then translating the camera to view them at a reasonable distance. Now I’ve decided to starting using 3DS models and noticed that the vertex values range in a lot of them are in the thousands (-1400 to 1400).

Is there something inherently wrong with me limiting my models to such a small range? Will floating point precision cause problems if my numbers get too small?

I’m just trying to ge a feel of what a good range would be and build all models relative to those numbers.


Its pretty irelevant, you can always scale the 3DS models as you read them in. so long as were not talking 10^20 or anything silly!
