Physical Joint Limits
General Introduction
Each of human body bone has its own rotation limit, such as elbow and calf, they can only rotate in 1 DOF(degree of freedom). So we need to setup the physical joint accroding to the real situation.
Attribute Meaning
And the same attribute name maybe have different meanning if the different joint type. The swing attribute cannot be the negtive value.
Joint types and limit attributes
Instructions
Ball Joint
Ball joint can swing in 2 DOF and twist (sum 3 DOF)
Ball joint example
Ball joint swing and twist limit
Once select the physical joint, it will become to a visible manipulator
Left non-selected, Right Selected
The ball joint setup (Blue: swing down, red: swing up, yellow and purple: twist in counter/clockwise)
(From left to right) Small range of rotate, middle range or rotate, wide range of rotate
Shoulder joint
Shoulder joint can swing only (2 DOF), cannot twist
Shoulder joint limit, swing up and down limit
Hinge joint
Hinge joint can rotate around 1 axis (1 DOF)
Hinge example
Hinge joint rotation limit (the right one: can be rotate back easy but cannot rotate to forward)
