Collision detection

What is collision detection?
The collision detection algorithmically calculates the impact time by identifying two or more object intersections. Collision detection is also a virtual interface that determines user and object distance to avoid collision. Collision detection is a key component in 3D associated with robotics, video games, and physical simulation.

Collision detection concepts are based on computational geometry and linear algebra and include the following methods: Vector usage: Measures object distance and calculates length using the square root of the sum of squares of each vector component. Divides each vector component by vector size, which is a sum of 1.

Plane recognition: Easily identifies 3D spherical collisions, as an individual comparison of complex model polygons is not required. Physical simulators: Detects collision events before the collision event (priori) and after the collision event (posteriori). Collision detection events are detected by network nodes and recovered using protocols such as Carrier Sense Multiple Access / Collision Detection (CSMA / CD).
