SIGGRAPH Tech Talk: Modeling Asteroid (101955) Bennu as a Real-time Terrain

Using a commercial terrain engine [Englert 2012], this presentation shows how to model the complex surface of asteroid (101955) Bennu [Science 1999] with a hybrid approach that combines digital elevation models with static and dynamic displacement. Then we show how to adapt tri-planar material mapping (TRIMAP) to the curvature of planetary bodies, in order to effectively avoid all inherent texturing artefacts.
