The Medial Axis of a Multi-Layered Environment and its Application as a Navigation Mesh

Autor: van Toll, W.G., Cook IV, A.F., van Kreveld, M.J., Geraerts, R.J.

Path planning for walking characters in complicated virtual environments is a fundamental task in simulations and games. A navigation mesh is a data structure that allows efficient path planning. The Explicit Corridor Map (ECM) is a navigation mesh b

Publikováno v: Computer Animation and Virtual Worlds, 28(3-4). John Wiley and Sons Ltd

The k-nearest neighbour (kNN) problem appears in many different fields of computer science, such as computer animation and robotics. In crowd simulation, kNN queries are typically used by a collision-avoidance method to prevent unnecessary computatio
