What are some easy to use 3d Fractal programs?
Fractals are never easy if you want a result that looks even half decent. You're gona have to buckle down and experiment till you know what you're doing.
By "fractals" you really need "procedural generators". Recently I came across this tool:http://oblige.sourceforge.net/It generates Doom maps of surprising quality. It's written in Lua and C++ and you should study it.

>>566879You've never tried it.
It generates an almost infinite amout of maps of this quality and also monster placement, red, bue, yellow door and key placements, munitions and weapons taking into account the kind of mosters in every area and so on.
