I have not found documentation that explains 3D collision & physics. Although Java 3D provides its own built-in collision detection classes, they are either incorrect or inefficient. The solution to this problem can be used to solve the collisions of billiard balls on a pool table, the collision of a bullet fired with high velocity at a target in the distance, or a number of other common game scenarios in which the exact time and location of. These algorithms can be grouped into four approaches: space-time volume intersection. Detecting a collision needs to occur before the objects collide. This may help me with implementing OBB collision detection or other convex 3d shapes. This is a C++ code example for AABB structure:. When planning motions or deciding on certain actions, it is often important to see whether there are collisions with other objects at certain places within the game world, and often choosing the right collision for the job is the most important task of all. In this case, the complexity is O(k2), where k is the number of objects in the scene. See the Server Mode for more details. The z-buffer scheme doesn't seem to address collisions that are off screen. These include source, and most have limitations on commercial reuse: Bullet Physics Library - library for performing rigid-body collision detection and response. For this complicated situation, collision detection can be viewed as a two-phase process. This takes a little more processing time per collision, but not much, and the result is a much more convincing collision detection scheme. The class learns about collision detection on the computer. It can potentially save time in the collision detection process.
