- Objects are the building blocks of your scene. There are 20 different
- types of objects supported by POV-Ray. Seven of them are finite solid pri-
- mitives, 4 are finite patch primitives, 5 are infinite solid polynomial pri-
- mitives, 3 are types of Constructive Solid Geometry types and one is a spe-
- cialized object that is a light source.
-
- The basic syntax of an object is a keyword describing its type, some
- floats, vectors or other parameters which further define its location and/or
- shape and some optional object modifiers such as texture, pigment, normal,
- finish, bounding, clipping or transformations.
-
- The texture describes what the object looks like, ie. its material. Tex-
- tures are combinations of pigments, normals and finishes. Pigment is the
- color or pattern of colors inherent in the material. Normal is a method of
- simulating various patterns of bumps, dents, ripples or waves by modifying
- the surface normal vector. Finish describes the reflective and refractive
- properties of a material.
-
- Bounding shapes are finite, invisible shapes which wrap around complex,
- slow rendering shapes in order to speed up rendering time. Clipping shapes
- are used to cut away parts of shapes to expose a hollow interior. Transfor-
- mations tell the ray tracer how to move, size or rotate the shape and/or the
- texture in the scene.
