Collision Detection? Collision Detection? Determine if two virtual objects in the virtual world / environment intersect each other . If they do what will happen? Collision detection is the process of determining whether objects in the game world intersect with each other as well as the static geometry of the world itself (i.e. walls, floor, ceiling, etc). Collision detection prevents the player character and other objects from floating through other geometry like mist.

Collision Detection Background Collision Detection Background Collision detection involves contact analysis and spatial reasoning of static and/or moving objects. For many applications, collision detection is considered a major computational bottleneck. However, the problem of collision detection between moving objects is fundamental to simulations of the physical world

Some Examples of Some Examples of Applications Applications Robotics: Used to help steer the robot away from surrounding obstacles. Virtual Prototyping: Used to refine designs and their assembly without producing physical prototypes. Virtual Analysis: Can be used to simulate things that might be impractical or too expensive to conduct in real life, such as automobile crash testing. Task Simulation: Some tasks can not be practiced realistically without simulation, such as surgery and space station repair.
