I have just released a new version of my continental drift simulator.
The main improvements from version 1 (released 11 / 15 / 89) are:
- Added text-only mode to support nongraphics UN*X machines.
- Graphics ported to Sun 3 and 4 systems.
- Ported to IBM PC by Peter Lind.
- Parameters can come from an input file.
The source code is available from the USENET group comp.sources.misc, where
it is archived. It consists of two shar files.
TEC draws a map of some imaginary world and puts one big continent on it.
The program then graphically simulates the breakup of this supercontinent by
rifts and the drifting of the continents. Mountains are built by
subsuming and by continental collision, and are reduced by erosion. As
more time passes, the continents tend to drift back into a supercontinent
and split up again, forming what some authors call a "supercontinent cycle."
The program produces a map of an imaginary world which contains realistic
looking mountain ranges and continents which sometimes look like they fit
together (like South America and Africa on Earth).
Here's an example output file. 0's are ocean, 1's are land, 2's are
mountains. (Graphics output has up to 256 grey scales.)
