Eco Systems in Virtual Reality Applications

Due to their tremendous complexity, eco systems are a big challenge for graphics applications. Essentially every outdoor virtual reality application requires to display trees, flowers, grass and other natural objects, both believably and interactively.

In a collaboration with the University of Dresden, we developped a system for the interactive visualization of landscapes generated with the eco system modelling tool xfrog. With our current version we can render even highly complex scenes with more than 100 million triangles within a single view at interactive rates.


The following images were generated with our system on a 2x1GHz PC and an Nvidia GeForce3 graphics accelerator at 2 to 10 frames per second.
