I stumbled on the Pixar Library this afternoon and had to share. It is a great resource of research style papers explaining how to make everything work together. Among them is one that explains the collision system they built in order to have realistic grabbing of objects without dealing with the problem of penetration. The newest one is talking about a new multi touch system (common on cell phones and tablets now) that will aid in the setting of scenes. This isn't the typical "tips or tricks" we normally post but interesting stuff sometime deserves a look and this is well worth the read.
