procedural modeling

Procedural modeling is an umbrella term for a number of techniques in computer graphics to create 3D models and textures from sets of rules that may be easily changed over time. (Wikipedia, CC BY-SA)

Process that uses an explicit instruction set to produce a model outcome. The outcome of a procedural model can be recognized for its secondorder formational nature. In place of direct manipulation of design geometries, the procedural modeler rather directly manipulates an instruction set – or algorithm – that in turn produces design geometries.
