This post is part of my Game Physics Series. Contact Data GJK tells us whether two colliders are colliding and nothing more. In order to correctly resolve collision, we would need to generate contacts. As mentioned earlier, contacts are approximation … Continue reading →

This post is part of my Game Physics Series. As mentioned earlier, all collision detection algorithms are essentially determining if the CSO of two shapes contains the origin. The collision detection I am going to introduce to you here, the … Continue reading →

This post is part of my Game Physics Series. Configuration Space Object (CSO), a.k.a. Minkowski Difference or Minkowski Configuration Object, is a very important concept for collision detection. In addition to CSO, support function is an equally important mathematical concept … Continue reading →

This post is part of my Game Physics Series. As mentioned in this introductory post, a broadphase is the algorithm of choice to efficiently decide whether it is possible for two colliders to collide, without using the actual collision detection … Continue reading →

This post is part of my Game Physics Series. This post presents possible implementations of motion dynamics for a physics engine. For fundamentals of motion dynamics, please refer to this post. Rigid Body Interface Below is what a typical rigid … Continue reading →

This post is part of my Game Physics Series. Before delving deep into the programming aspect of physics engines,  I would like to first go over the fundamentals of motion dynamics. Unless specified otherwise, all discussion is in 3D. Also, … Continue reading →

This post is part of my Game Physics Series. I shifted from being the graphics programmer to being the physics programmer for my DigiPen game team half a year ago as we started developing our junior project. Knowledge on game … Continue reading →
