The series “2D Collision Detection for Game Programmers” is the definitive reference series for collision detection algorithms. In the first volume; “Focus on Point Collisions”, each of the three types of collisions will be defined: Static Collision, Semi-Dynamic Collision, and Dynamic Collision. The collision algorithms for points colliding with points, lines, horizontal lines, vertical lines, rays, segments, circles, ellipses, axis aligned bounding boxes (AABB), object oriented bounding boxes (OOBB), capsules, and polygons will be explored in detail. Each algorithm is complete with a clear diagram illustrating the collision, a descriptive list of steps that define the algorithm, and a Java implementation. This book is a must for any game programmers wanting to understand the details of collision detection.
