Detailed Description

Generic description of a contact point, used for most collision models except special cases such as GPU-based collisions.

Each contact point is described by :

• elem: pair of colliding elements.
• id: unique id of the contact for the given pair of collision models.
• point: contact points on the surface of each model.
• normal: normal of the contact, pointing outward from the first model.
• value: signed distance (negative if objects are interpenetrating).
• deltaT: estimated of time of contact.

The contact id is used to filter redundant contacts (only the contact with the smallest distance is kept), and to store persistant data over time for the response.
