Game Collision Detection: A Practical Introduction

By Kenwright

Collision detection is a challenging and important multi-discipline problem in robotics, medical analysis and most importantly video games. Collision detection is not just a true or false answer to the question if two objects are touching, it is essential to detect the physical geometric data between objects and the environment accurately, such as, contact points, penetration depths, and separating normals. In fact, not only does the collision data need to be accurate for games, it needs to be fast. We explain collision detection algorithm principles and implementation details for use in interactive environments and physic-based simulators. We explain basic mathematical concepts and geometric principles (e.g., vectors, cross product, and plane equation). This textbook is designed to introduce the reader to the exciting topic of collision detection in virtual environments from a practical perspective. Organized around the central concept of collision detection, the book includes numerous practical examples in the body of the text as well as explaining technical limitations and engineering solutions. It is also one of the purposes of this book to introduce the reader to the development aspect of game and real-time interactive software.

A new idea deserves a working example.

There is a strong reading opportunity in the space between Books and Computers & Technology. “Game Collision Detection: A Practical Introduction” brings those listed subjects onto the same shelf and gives your next question a place to start. Collision detection turns geometric questions into decisions a simulation must make. Start with two simple shapes and ask exactly what should count as contact. The exciting next step is practical: choose a small outcome connected to the topic, attempt it, and use the reading to sharpen your decisions. A modest project can make an ambitious subject feel much more tangible. Pick a question. Open a book. See where it takes you.
