Separate axis theorem
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.

Web7 Dec 2024 · Separating Axis Theorem is inconsistent. I recently implemented the SAT algorithm into my 2D game and at first it appeared to be working fine. However, when I move around and rotate the character in and out of the wall tiles, there are some angles and positions that do not register as a collision when the player and wall tile are clearly ... 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
WebThe Separating Axis Theorem is an implementation of the Hyperplane Separation Theorem used for detecting intersections in 2D and 3D, making it a useful efficient method for detecting collisions in games. You can read my Dissertation here, or download the project at my GitHub here. At the end of this project, I received a First grade for it.
