Spring constraint

Software; CAD

In dynamics, a constraint that simulates an elastic cord. Use spring constraints to create effects such as a man bungee-jumping off a building.

In animation, a NURBS or polygonal object that further shapes and controls the deformation of smooth skinned objects. Influence objects are useful to restrict undesirable deformations (for example, ...

Skeleton

Software; CAD

In animation, a structure that consists of joints and their bones, used to create hierarchical, articulated deformation effects on deformable objects such as NURBS surfaces.

Smooth skin

Software; CAD

In animation, a surface with smooth, articulated deformation, where several joints can influence the same deformable object points. Also known as local/global envelope.

Scrubbing

Software; CAD

In animation, the action of manually moving the current frame along the timeline to examine animation, without actually playing the animation.

Root joint

Software; CAD

In animation, the highest joint in a skeleton’s hierarchy. A skeleton can have only one root joint. Also known as root.

Skinning

Software; CAD

In animation, the process of binding deformable objects to a skeleton. The surface of a character after that surface is bound to the character’s skeleton is called the skin. It is important that a ...
