**-window**- Draw on a newly-created window. This is the default.

**-root**- Draw on the root window.

**-install**- Install a private colormap for the window.

**-visual***visual*- Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

**-delay***microseconds*- How much of a delay should be introduced between steps of the animation. Default 25000, or 1/40th second.

**-5-cell**- Display the 5-cell. The 5-cell is the 4d analogon of a regular tetrahedron in 3d. It has 5 regular tetrahedra as its cells, 10 equilateral triangles as faces, 10 edges, and 5 vertices.

**-8-cell**- Display the 8-cell (a.k.a. hypercube or tessaract). The 8-cell is the 4d analogon of a cube in 3d. It has 8 cubes as its cells, 24 squares as faces, 32 edges, and 16 vertices.

**-16-cell**- Display the 16-cell. The 16-cell is the 4d analogon of an octahedron in 3d. It has 16 regular tetrahedra as its cells, 32 equilateral triangles as faces, 24 edges, and 8 vertices.

**-24-cell**- Display the 24-cell. The 24-cell has no 3d analogon. It has 24 regular octahedra as its cells, 96 equilateral triangles as faces, 96 edges, and 24 vertices.

**-120-cell**- Display the 120-cell. The 120-cell has no 3d analogon. It has 120 regular dodecahedra as its cells, 720 regular pentagons as faces, 1200 edges, and 600 vertices.

**-600-cell**- Display the 600-cell. The 600-cell has no 3d analogon. It has 600 regular tetrahedra as its cells, 1200 equilateral triangles as faces, 720 edges, and 120 vertices.

**-wireframe**- Display the polytope as a wireframe mesh.

**-surface**- Display the polytope as a solid object.

**-transparent**- Display the polytope as a transparent object (default).

**-single-color**- Display the polytope in red.

**-depth-colors**- Display the polytope with a fully saturated color wheel in which the edges or faces are colored accoring to their average 4d "depth", i.e., the w coordinate of the polytope in its unrotated position (default).

**-perspective-3d**- Project the polytope from 3d to 2d using a perspective projection (default).

**-orthographic-3d**- Project the polytope from 3d to 2d using an orthographic projection.

**-perspective-4d**- Project the polytope from 4d to 3d using a perspective projection (default).

**-orthographic-4d**- Project the polytope from 4d to 3d using an orthographic projection.

**-speed-wx***float*- Rotation speed around the wx plane (default: 1.1).

**-speed-wy***float*- Rotation speed around the wy plane (default: 1.3).

**-speed-wz***float*- Rotation speed around the wz plane (default: 1.5).

**-speed-xy***float*- Rotation speed around the xy plane (default: 1.7).

**-speed-xz***float*- Rotation speed around the xz plane (default: 1.9).

**-speed-yz***float*- Rotation speed around the yz plane (default: 2.1).

**DISPLAY**- to get the default host and display number.

**XENVIRONMENT**- to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
