Human Joints

I’m sure every person who has made (or has attemted to make) a human has come across this sort of problem… what is the absolute best way to do joints? Very few tuts go into detail about this and it doesn’t always work that well. So here are some things that you would want in the “perfect” joint.

  1. Keeping it low poly.
  2. No clipping.
  3. Good deformation so no enormous polys forming.
  4. Last but not least, this is one I’ve been confused about. Almost all joints I’ve seen involve tris. Weren’t tris supposed to be evil? How should I place them? Should I even use them?

If someone could help, that’d be great! It would probably help a lot of other people too.
I was told to move this from the GES&D to the Animation forum so here it is. Hopefully someone will have an answer since this seems to be a problem for a lot of people. One thing I forgot to mention. Feel free to help with ANY kind of joint. Hip, knee, shoulder or whatever. It would be great if someone could get some images or examples up.
