For a sphere the path is rotation of a half-circle around a point.

For tori, rings, and tubes the path is a circle. For boxes, prisms, and cylinders the path is a line.

Prims are formed by moving a circle, triangle, or square through a path in 3D space. The properties of a prim face can be changed individually by using its face number or all of the prim faces can be modified at once using the ALL_SIDES face number. The texture properties that each face can have are: texture, texture map (standard or planar), scale, offset, and rotation.

Each face of a prim can have its own texture properties, color, alpha, and attributes ( shiny, full-bright, and bump-map). A prim has one or more faces (or sides) depending on its basic shape and shape parameters.
