Hi all,

Has anyone had a play with creating procedural landscapes or the like? I'd love to see examples of city block, rivers, entire continents - any environment done with a minimal definition, say an integer, that creates a whole area with fractals or some other method.

I'd like to have my trees actually defined as 2 levels - one as fractal generation of layout off a regularly spaced int, and a second layer of larger trees and landmarks placed manually. For this to work, i need to figure out a good way of having the grid-placed layouts spawned from minimal data.

Well, we are working on something like that but we are using some predefined bmaps for the principal relief of the entire world but it isn't finished yet.
I maybe show some results in a few weeks...
If you are experienced in 3dgs you can do it

Cool - thanks for the encouragement Puppeteer

i've once coded a plugin for 3dgs which set the vertices of a terrain to a procedurally created heightmap. i've not developped it further but took the code and made a standalone application.

I can see a procedural landscape generator being done in C++ as a plugin or part of a custom engine, but I need to make one for myself, and if it works I might release a DLL or something if I can, but I might not.

if you need some advice...

Sry to be a noob but if 3DGS supported DirectX 10 could something like this be done using a geometry shader?

You can just deform terrain using the vec thingy... Forgot what the function was called.

For the trees, you could write an action which spawns a cloud of trees around the big landmarked tree. Using a non-random algorithm to do this, a fractal could be used or something similar to generate trees around it.

it could be done, but the hard thing is not to write a geometry shader but to implement a perlin noise, fractal noise or whatever-ridged-multi-perlin algorithm.
