An object created by combining two objects using mathematical operators. The two objects may be subtracted from one other, merged, or intersected to form the new object.

(a)  

A modelling tool which deforms the structure of an entire object. However, the exact meaning of the term varies from software package to software package.

(a)  

A set of mathematical attributes that determine the ways in which the surface of a model to which they are applied reacts to light. These attributes are sub-divided into individual channels.

(a)  

The surface geometry of a 3D model, made up of a series of linked geometry elements such as polygons, patches or NURBS surfaces.

(a)  

A method of displaying 3D scenes adopted by many high-end software applications, in which a scene is shown simultaneously in Top, Side, Front and Perspective views.

(a)  

Used as a noun, it means the 3D object created as the end product of the modelling process.

(a)  

A set of 3D objects, including the models themselves and the lights and camera that will be used when rendering them out.

(a)  

The automatic alignment of one object to another or to a reference grid, intended to aid the precise placement of objects within a scene or modelling hierarchy.

(a)  

A simple three-dimensional form used as the basis for constructive solid geometry modelling techniques.

(a)  

A modelling technique in which a two-dimensional outline or profile is duplicated outwards along a linear path, and the set of duplicated profiles joined to create a continuous three-dimensional surface.

(a)  

A method of reducing or preventing rendering artefacts by using colour information to simulate a higher screen resolution.

(a)  

A bitmap image that is applied to the surface of 3D object to give it detail

(a)  

The process of binding the surface of a model to the underlying skeleton during character rigging.

(a)  

A shading method in which a simple grid of lines is used to represent the basic contours of the underlying model.
