Separate axis theorem
Web23 Feb 2024 · Separating Axis Theorem Collision Performance While some of these algorithms for collision detection are simple enough to calculate, it can be a waste of cycles to test *every* entity with every other entity. Usually games will split collision into two phases, broad and narrow. Broad Phase Web6 Aug 2012 · The Separating Axis Theorem is often used to check for collisions between two simple polygons, or between a polygon and a circle. As with all algorithms, it has its …
Separate axis theorem
Did you know?
The separating axis theorem can be applied for fast collision detection between polygon meshes. Each face's normal or other feature direction is used as a separating axis. Note that this yields possible separating axes, not separating lines/planes. In 3D, using face normals alone will fail to separate … See more In geometry, the hyperplane separation theorem is a theorem about disjoint convex sets in n-dimensional Euclidean space. There are several rather similar versions. In one version of the theorem, if both these sets are See more If one of A or B is not convex, then there are many possible counterexamples. For example, A and B could be concentric circles. A more subtle counterexample is one in which A and B are both closed but neither one is compact. For example, if A is a closed half … See more In collision detection, the hyperplane separation theorem is usually used in the following form: Regardless of dimensionality, the separating axis is always a line. For example, in 3D, the space is separated by planes, but the … See more • Collision detection and response See more Note that the existence of a hyperplane that only "separates" two convex sets in the weak sense of both inequalities being non-strict obviously does not imply that the two sets are disjoint. Both sets could have points located on the hyperplane. See more Farkas' lemma and related results can be understood as hyperplane separation theorems when the convex bodies are defined by finitely many linear inequalities. More results may be found. See more • Dual cone • Farkas's lemma • Kirchberger's theorem See more Web16 Dec 2008 · In 2D space, the Separating Axis Theorem states two convexpolygons do not intersect if and only if there exists a line such that the projections of the two polygons onto the line do not intersect. The line is known as a separating axis. Consider rectangle A and rectangle B in the illustration below.

Web19 Apr 2014 · With SAT based CD I believe you should be projecting all points onto your separating axes. As the scene evolves you should be changing the axis vectors you use. These are the normals of the faces in your scene. As the cubes rotate, the separating axes rotate.
