Minkowski Portal Refinement and Speculative Contacts in Box2D
A physics rigid body simulation engine is a fundamental component of today’s
videogames. There have been recent advancements in the fields of collision detection
and collision resolution with supposed performance gains. In this paper we evaluate
Minkowski Portal Refinement,a new collision detection routine against GJK, the current
standard. We also evaluate the speculative contacts technique for performance and
behavior against Box2D’s “conservative advancement” continuous collision detection
