|Specifys the display in the usual way.|
|Sets the size and location of the t3d window.|
|Modifies the direction move of t3d. The clock looks 30 degrees* factor to the left and to the right periodically.|
|Modifies the wobbling (sounds nice :-) of t3d by multiplying the default deformation of the clock with factor.|
|Renices t3d by factor because t3d uses your process time. The default renice factor is 20, so you cant do anything wrong with not renicing t3d. If you want more speed, you should set nice to a smaller value.|
|Shows one small ball for every minute, instead of one for every 2.5 minutes.|
|Changes the magnification of t3d. By default, t3d uses a 200x200 window. A factor of 2 means, it will use a 400x400 window.|
|Sets the moving cycle to period seconds. By default, this value is 10 seconds.|
|Inserts a wait after drawing one view of the clock. By default, t3d waits 40 ms after each drawing. This helps you to keep the performance loss small.|
|t3d uses bitmap copy to draw precalculated balls. You can specify the radius in pixels up to which t3d should precalculate balls. t3d will set a useful range by itself using the magnification when it is started.|
|Draws cyclic the color scale used for the balls in the background instead of the normal black.|
|-rgb red green blue|
|Selects the color in RGB color space of the lightning spot on the balls. All the other colors used for balls or -colcycle are less intensive colors of the same hue and saturation. All values in range of 0 to 1.|
|-hsv hue value saturation|
|Selects the color in HSV color space. hue is in degrees from 0 to 360, all other values in range from 0 to 1. It gives nice but rather unpredictable results, if you use a saturation of e.g. 2. Try it at your own risk.|
|Rotates the hue axis every 10 seconds* speed.|
Prints a short usage message.

T3D is not related to T3D(tm), the massive parallel Alpha--based supercomputer from Cray Research. T3Ds name was invented in 1991, years before the project at Cray Research started. There is no relation from T3D to Crays T3D, even the balls surrounding T3D on some posters werent an inspiration for T3D. I dont know anything about the other way round.
The programming style of T3D isnt intented as example of good style, but as example of how a fast prototyped demo may look like. T3D wasnt created to be useful, it was created to be nice.
There are no known bugs in T3D. Maybe there are bugs in X. Slight changes in the T3D sources are known to show these bugs, e.g. if you remove the (int) casting at the XFillArc x,y,w,h-coordinates...
