2013 Rivers

Image ImageRivers have been automatically generated by computing the drainage network over a given input domain.
The final elevation model representing the hills and moutains were derived from the river network to guarantee a geomorphologically consistent watershed.

2011 Roads

Image ImageCountryside roads have been automatically generated from the terrain and ecosystem data structures by computing an anisotropic shortest path minimizing the weighted influence of the vegetation, the slope and the rivers.

2010 Eurographics Cover Competition

Image

This image won the first prize of the Computer Graphics Forum 2010 Cover Competition. It represents a grasping hand made of small stones. This complex model, featuring 17,504 stones (2,315,840 triangles), was automatically created from a simple mesh model. We use an aperiodic tiling method for generating the stones into contact without any computationally demanding physically-based simulation.
Our approach relies on a modified corner cube algorithm to generate a set of aperiodic tiles, which enables us to avoid visually disturbing repetitive patterns. Our model allow us to control the shape as well as the relative orientation and size distribution of the stones.

2010 Rocks and stones

Image Image ImageRocks and stones have been generated procedurally from a coarse three dimensional model representing the huts.
