View Full Version : colision detectio

05-01-2003, 02:45 PM
I am working ona a game with characters using swords in open GL. I use various spheres to determine the outline of the objects and then test the colision of each sphere with other spheres.

Is this the correct way of determining colisions?

That is a semi-efficient way to calculate collisions. Another is to use bounding boxes.

To get the true collisions is very expensive, and would likely be detrimental to your real-time rendering (assuming you have a decent number of possible collisions going on).

I believe that most people have a simple bounding object (sphere or box) to perform collisions. What kinds of objects are you colliding? The sword and what? A box may be a better fit for an object like a sword - it can give slightly more accurate collisions.
