( An early high performance algorithm for this was developed by Ming C. Lin at the University of California, Berkeley [1], who suggested using axis-aligned bounding boxes for all n bodies in the scene. In addition to the a posteriori and a priori distinction, almost all modern collision detection algorithms are broken into a hierarchy of algorithms.

For a long time, video games had a very limited number of objects to treat, and so checking all pairs was not a problem. j T 1 + , ) , ) If 3 Almost all games use a posteriori collision detection, and collisions are often resolved using very simple rules. , ) in 1 R P and So now, we have two sets of triangles, c := ( {\displaystyle E} y . Given a force applied to the cue ball (probably resulting from a player hitting the ball with his or her cue stick), we want to calculate the trajectories, precise motion, and eventual resting places of all the balls with a computer program. 4 3 {\displaystyle S} , The most widely used family of algorithms is known as the hierarchical bounding volumes method. x 2 and intersects v I 2 x ) y {\displaystyle m_{ij}} m When the time comes for testing a pair of objects for collision, their bounding sphere tree can be used to eliminate many pairs of triangles. x , and we can calculate (ahead of time) the bounding spheres A {\displaystyle J_{k}} Often the terms "discrete" and "continuous" are used rather than a posteriori and a priori. , r , y , ) / , ) And, if, for instance, That is, if the triangles are ] So now, we have two sets of triangles, As a precomputation, we can take each physical body (represented by a set of triangles) and recursively decompose it into a binary tree, where each node d [ v .

A and − ∧ 1 ) [3] Bounding boxes are typically used in the early (pruning) stage of collision detection, so that only objects with overlapping bounding boxes need be compared in detail. 3 Castlevania: Lament of Innocence is an action-adventure video game developed by Konami for the PlayStation 2 console. To exploit this, the list of intervals is actually maintained as a list of labeled endpoints. 1 . × ( 1 , ) {\displaystyle j} ( Collision Innocence Collision Innocence Game Controversy FAU-G Fau-G Game New Game Online Game Pubg Pubg Mobile PUBG Online अपड ट ब ट न … v ( 6 2 {\displaystyle (x_{2},y_{2},z_{2})} {\displaystyle {v_{4}(t),v_{5}(t),v_{6}(t)}} {\displaystyle \land (A_{z}-A_{rz}\leq B_{z}+B_{rz})\land (B_{z}-B_{rz}\leq A_{z}+A_{rz})}, AABB方式は2Dの衝突判定を取る場合でも使われることがある。特に四角いヒットボックスと円形のヒットボックスの衝突判定を取る時は、四角いヒットボックスの座標をAABB方式で管理した方が楽である。, 2Dゲームにおいて、ピクセル単位で衝突判定を取る方式。スプライト画像をベースとする衝突判定の方式なのでimage-based collision detectionともいう。1980年代頃までの8bit機ではスプライトの表示位置ごとの衝突判定を取ることしかできなかったが(当時のスプライトの大きさは基本的に8x8であったため、8ドット単位の衝突判定になった)、この方式を用いることで、1ドット単位の衝突判定が可能になる。, MSX2(1985年発売)の「スプライトモード2」ではハードウェアの支援が得られることがウリの一つであった。ハードウェアの支援が得られないハードにおいてソフトウェアベースでピクセルパーフェクトを実現する方式がいくつかあるが、現代においてこれをソフトウェアで実装するには、基本的には複数のヒットボックスを組み合わせて衝突判定を取る方式が用いられる。そもそも現代の2Dゲームエンジンでは8bit機時代のようなスプライト機能をソフトウェア上で擬似的に実装しているだけであるので、現代のハードウェアの性能をもってすれば、ソフトウェアベースでピクセルパーフェクトを実装することは特に困難ではない。, 複雑な形状のポリゴンモデルの衝突判定を行うとき、ポリゴンモデルを「複数の球の組み合わせ」とみなし、それぞれの球において衝突判定を行うことでオブジェクト同士の衝突判定を行うことができる。セガの初代『バーチャファイター』(1993年)で初めて実装された手法[6]。現在はポリゴンのキャラクター同士の衝突判定を取る際の基本的な手法であるが、これが初めて実装された1993年当時は衝撃的であったとのこと(『バーチャファイター』以前のゲームは、各キャラクターの姿勢や動作の一つ一つについてヒットボックスを個別に実装していたため、メモリを食う上にキャラクターの見た目と衝突判定が一致していなかった)[7]。, バイナリ空間分割木(Binary space partitioning, BSP木)を用いる方法。広大な3D空間において衝突判定を行いたい場合、空間をいくつかの区画に分割して刈り込む、と言う方法を取る。, 上記の衝突判定ではすべて、オブジェクト同士が衝突しているかどうかを「1フレームごと」にチェックする、つまり「離散的(Discrete)」な衝突検出法を用いた。1フレームごとにしか衝突判定を行わないことで、高速な衝突判定が行えるが、しかしこの方式を用いた場合、オブジェクトが速すぎてヒットボックスが1フレーム以下の時間で壁を通り過ぎてしまって衝突判定が行われない、トンネリング(いわゆる「壁抜け」)が起こりがちである。それを防ぐためには、1フレームごとに離散的に衝突判定を行うのではなく、連続的に衝突判定を行う「連続的衝突判定」(Continuous Collision Detection, CCD)と言う手法を取るのが一般的である。そのための最も一般的な手法がこれである。, オブジェクトを球体で近似する。この球が、現在の速度で直線的に動くと考え、「ある点」から「ある点」まで移動することで出来る軌跡を考える。この結果できた、カプセルのような形をしたボリューム(掃引体)のことを「球体スウィープボリューム(sphere-swept volume:SSV)」と言う。このボリュームが別のオブジェクトと接触していた場合、衝突が発生していると考えられる。, 球体スウィープボリューム同士の衝突判定を行うことで、高速に動くオブジェクト同士の衝突判定も行える。動く球同士の衝突判定の取り方を説明すると、動く球は、移動開始時の中心・速度ベクトルV・半径、で表すことができる。現在のフレーム(フレーム0)と次のフレーム(フレーム1)の間の時間において、0 < t < 1 となる媒介変数 t を使うと、球Aの中心は (A0 + t Va), 球Bの中心は (B0 + t Vb) と表せる。このように動いていく球A・球Bの中心どうしの距離が、半径の和以下になるような時刻 t が存在するか?
