Any real-time 3D InteractionProgramIf there is no collision detection, it is of no value or even unusable. The most common Collision Detection Technology in the game is bounding volume collision detection. For games running at 60pfs, it takes only about 0.0167s to process each frame of data. For different games, collision detection takes about 10-seconds ~ 30% of the time, that is, all collision detection must be between 0.002 and ~ Within s, it was a huge challenge. Therefore, any box should me
1) AABB bounding box: AABB bounding box is aligned with the axis of the bounding box, the simplicity of good, poor tightness (especially in the diagonal direction of the elongated shape of the object, the use of AABB, will leave a very large corner gap, resulting in a large number of not required bounding box intersection test). When the object rotates, the AABB should be rotated and updated. Once the object is deformed, it is only necessary to calculate the bounding box of the deformed basic ge
find that there is a rule that the two rectangular intersection must have a vertex in the other side of the graph to determine whether the rectangle contains a point this simple: as long as the point to the rectangle 4 and the distance of the sum is equal to the length and width of the rectangle and (high school mathematics knowledge) But judging above these is not to say the realization of the end, Game on performance requirements, and there are corresponding algorithms, Aabb,
In the cocos2dx of the collision detection of the rectangle needs to do a collision check of the rotated rectangle, because the game does not use the box2d and other physical engine, so the obb (oriented bounding box) direction bounding box algorithm, the algorithm is based on the SAT ( Separating axis theorem) separates the Axis law. Separation Axis law: Two convex polygon objects, if we can find an axis, so that two objects on the axis of the proje
How to perform collision detection on a 2D rotating rectangle, you can use a detection algorithm called OBB (oriented bounding box) to enclose the box in the direction. The algorithm is based on the SAT (separating axis theorem) separation axis law. The OBB is not just a collision detection of a rectangle, but an algorithm model. Simply explain the concept, bounding box and separation axis law. Bounding box

StorageManagerStorageManager is the interface to the systems storage service. The storage Manager handles storage-related items such as Opaque Binary Blobs (Obbs).Obbs contain a filesystem that maybe being encrypted on disk and mounted on-demand from an application. Obbs is a good a-providing large amounts of binary assets without packaging them into APKs as they could be multiple g Igabytes in size. However, due to their size, they ' re most likely stored in a GKFX storage pool accessible from
