I think a lot of people are overthinking character collision
detection and think you need volumetric representation
with sweep tests, etc.

When in actuality you can often get away with a few line
segment probes to detect collision with the world and use
a simple capsule test (or similar) to avoid character-
character interpenetration.

Keep it simple.
