Horde3D

Is it easy to implement a sphere query with Horde3D or is it necessary to modify the engine's sources?

Thanks to all!

If you want it to be optimal then you'd best do it in the engine. Castray() will provide a starting point for how it basically works. Then you just turn it into an evaluation of distance from a point.

Note: If you're using a collision detection library then you'll have this sort of feature for detecting collision primitives, it will also already be heavily optimized.

Thank you for your suggestions.
