Project Tierra

Amazed by the isosurface landscapes by Christoph Hormann, I tried to emulate his project Landscape of the week, and create an automated, parametrized scene to generate random landscapes.

It took me some time to get a setup fast enough to generate a landscape per week, but finally I learned to use isosurfaces with pigment funtions and complex sloped textures, and also developed other interesting techniques and little tricks.

Here are the succesive landscapes from past weeks. As you can see, I've abandoned the weekly updates some time ago. But recently I resumed this project, and I hope to release a second version. At the end of this page you can find the source code for the first version.

At the moment is very messy and not very well planed, but I hope it will be useful at least to give some ideas to other landscaping adicts. It doesn't necessarily renders any of the images showed.

These are some details about the techniques used:

Please, look at the include files for more details. If you only want to use it to trace landscapes, make a copy of tierra.pov and play with the parameters and random seeds (there are some hints on the comments). Be sure also to donwload Lightsys, as it is needed by many of the include files.
