Overview
This program renders 160 different 3D solids, and displays some information about each. A new solid is chosen every few seconds.
There are 75 uniform polyhedra, plus an inifinite number of prisms and antiprisms:
* Convex Uniform Polyhedra:
* Platonic solids (5)
* Archimedean solids (13)
* Convex prisms and antiprisms (2 infinite families)
* Nonconvex Uniform Polyhedra:
* Kepler-Poinsot polyhedra (4)
* Nonconvex uniform polyhedra (53)
* Nonconvex prisms, antiprisms, and crossed antiprisms
(3 infinite families)
Representative samples of the prism sets brings the total to 80 solids. Including the dual of each brings the total up to 160. (To create the "dual" of a polyhedron, faces are replaced with vertices, and vertices with faces.)
Options
-
--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.
-
--window -
Draw on a newly-created window. This is the default.
-
--root -
Draw on the root window.
-
--window-id number -
Draw on the specified window.
-
--delay number -
Per-frame delay, in microseconds. Default: 30000 (0.03 seconds.).
-
--speed number -
Larger numbers mean run faster. Default: 1.0.
-
--duration seconds -
How long before switching to a new polyhedron. Default 12 seconds.
-
--wander | --no-wander -
Whether the objects should wander around the screen.
- --spin [XYZ] | --no-spin
-
Which axes, if any, to spin around on.
-
--titles | --no-titles -
Whether to display text describing each object.
-
--which object-name -
Display only one particular object, identified by number, name, or Whthoff symbol.
-
--wireframe | --no-wireframe -
Render in wireframe instead of solid.
-
--fps -
Display the current frame rate, CPU load, and polygon count.
Key bindings
When running in a window, you can rotate the object with the mouse. Also, the following keystrokes are defined:
SPC or TAB
|
Select a new polyhedron at random. |
|---|---|
+ or >
|
Select the next-higher-numbered polyhedron. |
- or <
|
Select the next-lower-numbered polyhedron. |
ESC or ^C
|
Quit. |
Environment
-
XENVIRONMENT -
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
-
XSCREENSAVER_WINDOW -
The window ID to use with --root.
