- - A fractal landscape generator -
-
- - by Andrew Lewis -
-
- - Original Idea by Peter Millerchip -
-
- - Version 1.3b 28th October 1992 -
-
-
- Fracland is a fractal landscape generator, using pseudo random
- midpoint displacement to generate a landscape of "infinite"
- detail.
-
- Required Hardware:
- 286 PC or greater, running DOS 3.x or better
- 256K of RAM, almost guaranteed with 286's
- IBM VGA card or compatible, 16bit preferably
- A Microsoft serial mouse, or other rodent with a compatible
- driver. Really anything that supports Int 33h calls.
- A Hard disk is preferable
-
- To start Fracland, make sure the mouse driver is loaded, and type
- FRACLAND. The files FRACLAND.DAT and FRACLAND.DA2 must also be
- present.
-
- The program is very simple to use, just move the rectangle around
- the landscape and press the left mouse button to zoom in by a
- factor of two. Initially, a few zoomins are required before the
- landscape starts looking as it should. The buttons on the right
- are self explanatory, with the 3D option rendering the current
- landscape as a 3D isometric height field. Any very large heights
- are clipped. The Newland button restarts the landscape without
- having to exit the program. Also the colour of the landscape can be
-
- changed by clicking on the paint can icon.
-
- One of the effects of the algorithm used is that if you zoom in on
- just land or sea after a few zooms the landscape will break up, and
- very strange things can happen. This is due to the height of the
- point wrapping around from land to sea or sea to land. This will
- not occur in normal coastline zooming. If this does happen, then
- selecting NEW LAND will restart the landscape.

-
- This version is PC implementation of the program !FracLand2
- written for the Acorn Archimedes. This features a larger grid and
- a different light souring algorithm. It is also public domain and
- should be available from any Archimedes BBS, including The World
- of Cryton on +44 (0)749 670030. !FracLand2 was written by Peter
- Millerchip, who also produced the sprites for this version in
- !Paint on the Arc.

- Version History
-
- !Fracland - Original Archimedes desktop version, very slow and
- small grid size.
-
- !Fracland2 - New ARM code Archimedes version, on which the PC
- version was written in parallel.
-
- Fracland Version 1.0 - First PC version, no height changes or
- colour map or new land, also some strange
- bugs.
-
- Fracland 1.2 - Height change introduced to user-select roughness.
-
- Fracland 1.3 - New land and new colour palette options added. First
- full release.
-
- Fracland 1.3b - Small bug fix that should stop the program crashing
- on some machines (some 386's).

- And finally....
-
- A big "Hi" to Clare, Simon R, Husein G, David T and Rob V. Their
- derisive comments about my coding ability kept me going long after
- I might of given up!
