Linux for Designers

I'm a little bit late with it: InnerWorld, a landscape generator running inside the 3d suite Blender and uses internal noise functions and external height fields, is now available as alpha 0.0.6:
* Procedural object placement.
* User defined objects can be duplicated to populate the generated mesh.
* For calculating locations different strategies can be selected. Supported are grids, Poisson disk sampling and spirals.
* Random generators can add variations in size, locations and rotation of duplicated objects.

A tutorial about procedural object placement is available too.
