GLUT includes a number of routines for generating easily recognizable 3D
geometric objects. These routines reflect functionality available in the
aux toolkit described in the OpenGL Programmer\'s Guide and are included
in GLUT to allow the construction of simple GLUT programs that render
recognizable objects. These routines can be implemented as pure OpenGL
rendering routines. The routines do not generate display lists for the
objects they create. The routines generate normals appropriate for lighting
but do not generate texture coordinates (except for the solid teapot, teacup
and teaspoon). If VBOs should be used instead of the fixed function pipeline,
specify at least one of the attribute locations

Flavour of object rendering
Object is rendered as a solid with shading and surface normals.
Object is rendered as a wireframe without surface normals.
GLUT offers five types of objects:
- The five Platonic solids, see http://mathworld.wolfram.com/PlatonicSolid.html.
- A rhombic dodecahedron, see http://mathworld.wolfram.com/RhombicDodecahedron.html.
- Approximations to rounded objects.
- The classic teaset modeled by Martin Newell in 1975. Both surface normals and texture coordinates for the teaset are generated.
- A Sierpinski sponge, see http://mathworld.wolfram.com/Tetrix.html.
A cube centered at the modeling coordinates origin with sides of the given length.
A dodecahedron (12-sided regular solid) centered at the modeling
coordinates origin with a radius of
A icosahedron (20-sided regular solid) centered at the modeling coordinates origin with a radius of 1.0.
Render a solid octahedron (8-sided regular solid) centered at the modeling coordinates origin with a radius of 1.0.
Render a solid tetrahedron (4-sided regular solid) centered at the
modeling coordinates origin with a radius of
(freeglut only) A rhombic dodecahedron whose corners are at most a
distance of one from the origin. The rhombic dodecahedron has faces
which are identical rhombi, but which have some vertices at which three
faces meet and some vertices at which four faces meet. The length of
each side is
|Sphere' Radius Slices Stacks|
A sphere centered at the modeling coordinates origin of the specified radius. The sphere is subdivided around the Z axis into slices (similar to lines of longitude) and along the Z axis into stacks (similar to lines of latitude).
|Cone Radius Height Slices Stacks|
A cone oriented along the Z axis. The base of the cone is placed at Z = 0, and the top at Z = the given height. The cone is subdivided around the Z axis into slices, and along the Z axis into stacks.
|Cylinder' Radius Height Slices Stacks|
(freeglut only) A cylinder oriented along the Z axis. The base of the cylinder is placed at Z = 0, and the top at Z = the given height. The cylinder is subdivided around the Z axis into slices, and along the Z axis into stacks.
|Torus Radius Radius Sides Rings|
A torus (doughnut) centered at the modeling coordinates origin whose axis is aligned with the Z axis. The torus is described by its inner and outer radius, the number of sides for each radial section, and the number of radial divisions (rings).
A teapot with a given relative size.
(freeglut only) A teacup with a given relative size.
(freeglut only) A teaspoon with a given relative size.
(freeglut only) A Sierpinski sponge of a given level, where a level
0 sponge is the same as a
