Contact
Introduction
Contact represents the relation between a body part and a contactable object.
Body parts can have multiple bones and sub-parts (e.g. a hand has 1 bone (wrist) and 5 fingers (sub-parts)). Contact stores which bones under this part (bones of part and its sub-parts) are touching or are close to touch (entered).
If ContactDetection module is linked to a hand, it will handle contacts for all bones in that hand including finger bones.
If ContactDetection module is linked to an arm, it will handle contacts for arm's bones, hand bones and finger bones.
If ContactDetection modules is linked to both arm and hand, there will be duplicated contacts for hand and finger bones, which is not recommended.
Variables
Name: Name of the contact. Useful for debugging.
Detector: ContactDetection module which is responsible for updating this contact. This ContactDetection module is linked (as child module) to a body part.
Contactable: ContactableView that represents the object that is being contacted.
Special Parts Touching: How many bones are touching the contactable object and are linked to a part or sub-part that is specially involved in grasping.
Type:
None: 0 bones are entered.
Entered: At least 1 bone is entered. 0 bones are touching touching.
Touching: At least 1 bone is touching. Grasping is not detected.
Grasped: At least 1 bone is touching. Grasping is detected.
Entered Time: Elapsed time since at least one bone entered the contactable object.
Touched Time: Elapsed time since at least one bone touched the contactable object.
Grasped Time: Elapsed time since Contact.type
became Grasped.
Bones Entered: List of BoneModels that are near the contactable object.
Bones Touching: List of BoneCollisionModels that are touching the contactable object.
BoneCollisionModel
Bone: BoneModel which slave representation performed the contact.
Points: List of ContactPoints retrieved from the collision detection.
