- 3DBB and 3DBBH
- --------------
-
- These are two versions of the same program, the only difference being
- that 3DBBH uses the hi-res (two-color) mode while 3DBB uses the medium-
- res (four-color) mode. Both programs are written in BASIC, and source
- is provided.
-
- 3DBB is a 3-Dimensional Black Board. The intention is to provide an
- experimental environment for studies in 3-D animation and design. The
- system is "bare bones" at present, allowing for creation, rotation,
- skew, and save/restore, but no editing of existing figures as such.
-
- The program can only be learned by using it, but several example drawings
- are included to give you an idea of what to shoot for. To give yourself
- a demo, do the following:
-
- 1) Load the program (3DBB or 3DBBH).
- 2) Read the title screen, then press <SPACE> to bring up graphics.
- 3) Making sure your CAPS LOCK is on, strike R for Read-in a file.
- 4) Read in CUBE.
- 5) Once CUBE is up, use the X, Y, and Z keys as you like to rotate the
- cube in space.
- 6) Try this with the other demo drawings as well (especially SHUTTLE).
- On some of the more complex drawings (again, especially SHUTTLE) you
- will experience a noticeable time-lag in rotation. Even compiled
- BASIC has its limitations.
-
- Hitting Esc at any time will bring up the instruction screen.

-
- I hope you enjoy this program; 3-D has always held a fascination for me,
- and many of my current projects use the concepts I learned while writing
- this program. If you have any questions or comments (or even, gasp, a
- donation) please address them to:
