svg collision

Hi everyone,

This is a question that comes along a lot, but i can't seem to find a workable answer...

I'm needing to implement shape collision detection (shapes are imported svg's) as part of a space filling algorithm. I've done something similar in the past in flash, but it was always too slow and cumbersome which is why i'm now here enjoying processing!

Most of the collision detection guidance i have found deals with circles/rectangles, but i need to find a fast and simple way to do it with complex shapes.

Any help either practical or conceptual would be much appreciated,

cheers,

emile

Geomerative has intersection() and contains() for shapes:

I found the following recently. I thought it helpful or at least along the same lines.

Java General Poly Clipper

It has union, intersect, and xor csg operations.

Rick, if my memory serves me right, Geomerative is precisely using this library, wrapping it for easier use.

You are correct, thanks for pointing that out. Geomerative credits GPC on its site. I had downloaded Geomerative before (never really used it much yet) and never realized GPC was being used.

I just found this thread that I think may be helpful, though I haven't looked it over thoroughly yet.
