- Time 3D is a clock. It uses flying balls to display the
- time. This balls move and wobble around to give you the
- impression your graphic workstation with its many XStones
- is doing something.
-
- t3d uses mouse and keyboard to let you fly through the
- balls. Hit S\bS to speed up, A\bA to slow down, Z\bZ to zoom in and
- X\bX to zoom out. Use the l\ble\bef\bft\bt m\bmo\bou\bus\bse\be b\bbu\but\btt\bto\bon\bn to rotate to the
- left and the r\bri\big\bgh\bht\bt m\bmo\bou\bus\bse\be b\bbu\but\btt\bto\bon\bn to rotate the view to the
- right. Use the m\bmi\bid\bdd\bdl\ble\be m\bmo\bou\bus\bse\be b\bbu\but\btt\bto\bon\bn to change the optical
- axis and the moving direction. 0\b0 (zero) will stop you. Q\bQ
- quits.

- -\b-m\bmo\bov\bve\be _\bf_\ba_\bc_\bt_\bo_\br
- Modifies the direction move of t3d. The clock looks
- 30 degrees* _\bf_\ba_\bc_\bt_\bo_\br to the left and to the right
- periodically.
-
- -\b-w\bwo\bob\bbb\bbl\ble\be _\bf_\ba_\bc_\bt_\bo_\br
- Modifies the wobbling (sounds nice :-) of t3d by
- multiplying the default deformation of the clock
- with _\bf_\ba_\bc_\bt_\bo_\br_\b.
-
- -\b-m\bmi\bin\bnu\but\bte\bes\bs
- Shows one small ball for every minute, instead of
- one for every 2.5 minutes.
-
- -\b-m\bma\bag\bg _\bf_\ba_\bc_\bt_\bo_\br
- Changes the magnification of t3d. By default, t3d
- draws a 200x200 image. A .I factor of 2 means, it
- will use a 400x400 image.
-
- -\b-c\bcy\byc\bcl\ble\be _\bp_\be_\br_\bi_\bo_\bd
- Sets the moving cycle to _\bp_\be_\br_\bi_\bo_\bd seconds. By
- default, this value is 10 seconds.
-
- -\b-w\bwa\bai\bit\bt _\bm_\bi_\bc_\br_\bo_\bs_\be_\bc
- 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.
-
- -\b-f\bfa\bas\bst\bt _\bp_\br_\be_\bc_\ba_\bl_\bc_\b__\br_\ba_\bd_\bi_\bu_\bs
- 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

- it is started.
-
- -\b-c\bco\bol\blc\bcy\byc\bcl\ble\be
- Draws cyclic the color scale used for the balls in
- the background instead of the normal black.
-
- -\b-r\brg\bgb\bb _\br_\be_\bd _\bg_\br_\be_\be_\bn _\bb_\bl_\bu_\be
- Selects the color in RGB color space of the light-
- ning spot on the balls. All the other colors used
- for balls or -\b-c\bco\bol\blc\bcy\byc\bcl\ble\be are less intensive colors of
- the same hue and saturation. All values in range of
- 0 to 1.
-
- -\b-h\bhs\bsv\bv _\bh_\bu_\be _\bs_\ba_\bt_\bu_\br_\ba_\bt_\bi_\bo_\bn _\bv_\ba_\bl_\bu_\be
- Selects the color in HSV color space. _\bh_\bu_\be 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.
-
- -\b-h\bhs\bsv\bvc\bcy\byc\bcl\ble\be _\bs_\bp_\be_\be_\bd
- Rotates the hue axis every 10 seconds* _\bs_\bp_\be_\be_\bd_\b.
-
- -\b-h\bhe\bel\blp\bp Prints a short usage message.

- T3D is not related to T3D(tm), the massive parallel
- Alpha--based supercomputer from Cray Research. T3D's name
- was invented in 1991, years before the project at Cray
- Research started. There is no relation from T3D to Cray's
- T3D, even the balls surrounding T3D on some posters
- weren't an inspiration for T3D. I don't know anything
- about the other way round.

- The programming style of T3D isn't intented as example of
- good style, but as example of how a fast prototyped demo
- may look like. T3D wasn't 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...
