Topography 2.0 by Larry Blake
Requires Microsoft Windows, mouse, and the runtime for Visual Basic
3.0 (VBRUN300.DLL in \WINDOWS\SYSTEM).
This Visual Basic program uses random numbers to generate a landscape.
Each point on the map has a value which corresponds to an elevation
and a color. This value is related to the values of the surrounding
points, plus a small random increment up or down. I have chosen
colors which should be familiar to users of topographic maps:
White (snow) / \
Light grey (rocks and snow) |
Dark grey (rocks) |
Brown (tundra) Elevation
Yellow (sparse vegetation) |
Green (plains) |
Blue (water) |
Future enhancements, in no particular order:
1. Windows screen saver.
2. Multi-pass calculation, with each pass calculating smaller
squares. This would reduce the overall jaggedness.
3. Button to pre-draw a river network.
4. Smooth curves instead of squares on 2D map. Isolines.
5. Improved perspective on 3D map.
6. Removal of hidden lines on 3D map.
7. Full color on 3D map (not just wire frame).
8. Shadows on 3D map.
9. Clouds on 3D map.
10. Roads and bridges on both maps.
11. Printing.
12. Save / Load capabilities.
