3D Collision Detection with 2D Terrain Maps
A. Sherstyuk, Kiyoshi Kiyokawa, Yuki Yano · 2013
Terrain elevation maps can be efficiently used for real-time collision processing for ground-bound travelers Maps. We extend this approach to handle objects that may fly freely in 3D space. The new algorithm makes effective use of allocated terrain image memory and does not require extra storage. It is easy to implement into any travel processing system.
