Скачать или смотреть 3D Collision Detection & Response for Video Games using Spheroids/Ellipsoids

Shows an example of collision detection and response using ellipsoids (spheroids) to capture player/character movement in a 3D environment. The idea is to use simplified geometry to simplify and speed up this process in video games.

The character movement is captured via a spheroid traversing (using basic physics) through a "polygon soup". Contact information is displayed in the form of collision surfaces and "normals". Collision surfaces/features include edges and triangles highlighted in blue/green (wireframe). The normals are represented using white and yellow lines to show which direction these features are facing and the character movement is being restricted.

The assets used in this video were created by me using blender 2.72, and the game engine used is my own custom engine written in c.
