Inverse Kinematics
IK rigging is the reverse process from forward kinematics and is often used an efficient solution for rigging a character's arms and legs. With an IK rig Erik McCoy Saints Jersey , the terminating joint is directly placed by the animator, while the joints above it on the hierarchy are automatically interpolated by the software.
IK is most appropriate when the animation calls for a terminating joint to be placed very precisely character climbing a ladder is a good example.
Because the character's hands and feet can be placed directly on the ladder's rungs rather than the animator having to adjust their position joint-by-joint, an IK rig would make the animation process far more efficient. One drawback is that because IK animation uses software interpolation, there's often quite a bit of cleanup work that must be done in order to finalize the shot.
Degrees of FreedomConstraints
When rigging, keep in mind that joints like the elbows and knees limited to a single degree of freedom in the real world Alvin Kamara Saints Jersey , meaning they can only bend along one axis. Likewise, a human neck cannot rotate a full 360 degrees.
To help prevent unrealistic animation, it's a good idea to set up joint constraints when you're building your rig. We'll address this further in a tutorial.
Squash and Stretch
Another consideration that must be made is whether the rig will support squash and stretch, or whether the character will be constrained to realistic motion. Squash and stretch is an important principle in exaggerated cartoon animation, but typically doesn't look right in realistic filmVFX work. If you want your rig to maintain realistic proportions Marshon Lattimore Saints Jersey , it's important to set a constraint to lock the position of each joint in relation to the rest of the rig.
Facial Rigging
A character's modelling facial rig is usually altogether separate from the main motion controls. It's inefficient and incredibly difficult to create a satisfactory facial rig using a traditional jointbone structure, so morph targets (or blend shapes) are usually seen as a more effective solution. Facial rigging is a topic in and of itself, so be on the lookout for an article exploring the subject in depth.
