Primitives vs. Procedural Objects

---

Bryce's Create palette lets you create two different types of basic object: Primitives and Procedurals.

Primitives are basic geometric shapes such as the sphere, torus, cylinder, cube, pyramid, cone, plane, and disk. These shapes can be thought of as primary geometric building blocks, from which more complex objects are constructed.

Primitives also have derivative groups (such as the ellipsoid and squashed sphere, which are derived from the Sphere), which allow you to create different shapes without having to perform the transformations yourself.

Procedural objects are object that require special constructions, or "procedures," to create, such as terrains, trees, rocks, symmetrical lattices, and Metaballs. Procedures can include operations such as preassigning materials, randomizing internal parameters, or assigning light properties.
