FAST 3-D LANDSCAPES A Bizarre Freeware Program For the 64K ZX/TS with 8K SRAM By Fred Nachbaur MUMAP This is something of an afterthough. It lets you do 3- dimensional Mandelbrot set plots, as well as the usual 2-D ones we have all grown to know and love. (“Mu-map“ was Benoit Mandelbrots original term for what was later named the “Mandelbrot Set“ in his honour.) You can even do composites of Mu-maps and Scope maps, for even more realistic-looking 'scapes! There is good reason why [M]umap appears before [S]cope in the Map menu. This is that creating a Mu-map over-writes the map array. Scope maps, on the other hand, are additive. In other words, you can do a Scope-scape using one set of parameters, then do another without first [C]learing the old map. The new map will simply be algebraically added to the old map. You can use this, for example, to make some rolling hills and valleys (high Z), then add sharper peaks and dips (low Z). The process can be continued ad infinitum, or until you mess up the map by overflowing 16- bit arithmetic.
