A novel collision detection algorithm of abrasive belt grinding blade integrated disk (blisk) based on improved octree segmentation is proposed, to improve the accuracy and efficiency of collision detection while ensuring dimensional accuracy and surface quality. The traditional collision detection algorithm...
This does mean we have to update the detection algorithm since it currently only works between two AABBs. Detecting collisions between a circle and a rectangle is a bit more complicated, but the trick is as follows: we find the point on the AABB that is closest to the circle, and if ...
In the a priori methods, we write a collision detection algorithm which will be able to predict very precisely the trajectories of the physical bodies. The instants of collision are calculated with high precision, and the physical bodies never actually interpenetrate. We call this a priori because...
The PhysX SDK supports an alternative CCD implementation based on simple raycasts. This "raycast CCD" algorithm is available in PhysX Extensions, and it is demonstrated in a snippet ("SnippetRaycastCCD"). Contrary to the built-in CCD algorithm implemented within the PhysX SDK, this cheaper and ...
Another algorithm that lends itself to parallel implementation is uniform grid collision detection. In its basic form, the algorithm assumes that all objects are roughly equal in size. The idea is to construct a uniform 3D grid whose cells are at least the same size as the largest object. 图...
Collision Detection是Rigidbody中的一个属性。所以显然Collision Detection指定的类型只在Rigidbody之间才有用。 1、Collision Detection用来干什么? Used to prevent fast moving objects from passing through other objects without detecting collisions. 用于阻止快速移动的objects因没有检测到collision而导致穿透other objec...
The collision detection algorithm is the core component of a numerical method aiming at computing the motion of non-spherical rigid bodies that collide. While elementary in the case of two spheres, collision detection of two non-spherical particles is far more challenging. Note that the problem of...
