【计算几何】凸多面体重叠判断算法:GJK 算法详解 & C++代码实 …
2023年1月21日 · 运用:GJK算法的核心就是闵可夫斯基差,即若两个多边形相交,则它们的闵可夫斯基差必然包括原点. 下面来看两个例子: 第一个例子:下图展示了多边形A和B相交的情况,他们的闵可夫斯基差包含原点. 第二个例子:下图展示了多边形A和B不相交的情况,他们的闵可夫斯基差没有包含原点. k 阶单纯形(simplex),指的是k维空间中的多胞形,该多胞形是 k+1 个顶点组成的凸包。 在 GJK 算法中,单纯形被大量使用。 单纯形指的是点、线段、三角形或四面体。 …
碰撞检测算法之GJK算法 - 知乎 - 知乎专栏
在精细碰撞检测阶段,除了 SAT 算法,另外一个就是 GJK(Gilbert–Johnson–Keerthi) 算法。 相比 SAT 算法,GJK 算法更加高效。 在介绍 GJK 算法之前,我们需要先了解一些背景知识。 凸多边形的定义:对于平面上的一个多边形,如果延长它的任何一条边,都使整个多边形位于一边延长线的同侧,这样的多边形叫做凸多边形。 根据上述定义,人可以直观判断出一个多边形是否为凸多边形,但在程序中,如何判断一个多边形是否为凸多边形呢? 答案是利用向量的叉乘。 如下 …

the Gilbert–Johnson–Keerthi algorithm explained as simply as …
We've ended up with a new set that represents the "difference" between A and B. Since it contains the origin, we know that there must be at least one pair of points whose difference is 0. That's exactly what the GJK algorithm takes advantage of.
GJK: Collision detection algorithm in 2D/3D - winter.dev
One popular algorithm for testing collisions is the Gilbert-Johnson-Keerthi algorithm, or GJK for short. With it we can detect collisions between any two convex polygons. The GJK algorithm is very useful and widely used, but no good visualization or concise explanations exist for …
J(英文字母)_百度百科
物理 中,j代表 焦耳 (j),简称焦,能量、功、热的单位符号。 1J=1N·m, 即1 牛顿 力的作用点 在力的方向上移动1米距离所作的功为1焦耳。 1J=1w·s=1A·V·s,即1瓦的机械工作1秒的释放的能量为1焦耳,3.6*10^6J= 1kwh ,即1度,是电的 常用单位 。
