Detailed Description

Specialized SLNode that represents a single joint (or bone) in a skeleton.

The main addition of SLJoint to the base SLNode is the offset matrix. The offset matrix is the inverse transformation of the joint's binding pose in mesh space. It is used to transform the vertices of a rigged mesh to the origin of the joint to be able to manipulate them in the join's space. The ID of the joint must be unique among all joints in the parent skeleton.
