PPT-Collision Detection and Resolution

Zhi Yuan Course Introduction to Game Development zyuancskentedu 11282011 1 Overview Collision Detection Identify the intersection of objects Collision Response Calculate . How to do this?. Here is where my object is. Here is where my object is going to be. Here is where I want my object to be. A box that is . Defined by the min and max coordinates of an object. Always aligned with the coordinate axes. Have a black-box function that returns a bright color in 24-bit RGB. Want a paler version of the output. What to do?. Collision Resolution.
