Collision Detection

Chapter

Overview

Collision detection is an integral component of game engines that are designed to provide realistic animations of object interactions with the player and the game environment. Physically realistic dynamic simulations such as flight simulators and mobile robot simulators also require efficient collision detection algorithms. Intersection tests form the backbone of collision detection algorithms. They are also used in ray tracing algorithms, acceleration algorithms such as view frustum culling and portal culling, and in real-time animations. This chapter gives an extensive coverage of methods used for testing if primitives and bounding volumes overlap.

Collision detection in a large scene consisting of several objects requires efficient methods to minimize the number of intersection tests. This chapter discusses the usefulness of bounding volume hierarchies and spatial partitioning trees such as octrees, k-d trees and bounding interval hierarchies, and includes a coverage of important algorithms in each category.
