Non-uniform rational b-spline (NURBS)

Software; CAD

A type of geometry that includes curves, patches, surfaces, etc. NURBS are a superset of conics, splines, and Bezier curves. They are particularly suited for modelling in 3D, because they provide ...

Outliner

Software; CAD

A window that lists the objects, lights, cameras, and other items in a scene. The outliner can be used to examine the structure and components of the scene hierarchy, display shape nodes, ...

Occlusion culling

Software; CAD

An occlusion is a visual obstruction, occurring when an opaque surface prevents another surface from being seen. Occlusion culling is a technique of improving shading display performance by not ...

Geometric configurations that, if unfolded, could not lie flat on a plane without overlapping pieces. Typically this situation occurs if the surface consists of several patches sharing a boundary. ...

Normal constraint

Software; CAD

In animation, a constraint that keeps an object’s orientation so that it aligns with the normal vectors of a NURBS or polygonal surface (mesh). Normal constraints are useful for keeping an object ...

Orient constraint

Software; CAD

In animation, a constraint that matches the orientation of one object to one or more other objects. Orient constraints are useful for keeping objects aligned.

Nonlinear deformer

Software; CAD

In animation, a deformer that acts independently of time. Nonlinear deformers in Maya include: end, flare, sine, squash, twist, and wave. Also known as geometric/deferrable, modifier-based, or ...
