Abstract. We present an approach for modeling and realtime rendering of outdoor scenes, for use in virtual reality applications such as flight simulators and multi-user virtual env...
For quantitative examination of phenomena that simultaneously occur on very different spatial and temporal scales, adaptive hierarchical schemes are required. A special numerical ...
Soft objects are often desired in applications such as virtual surgery training. Soft object simulations are computationally intensive because object deformation involves numerica...
