Collision response refers to how objects interact when they collide in a physical environment. This concept is crucial in fields like physics, computer graphics, and game development, where understanding the forces and motions involved helps create realistic simulations. When two objects collide, their velocities, angles, and material properties determine how they will react, such as bouncing off each other or crumpling together. In game engines, collision response algorithms calculate the outcome of these interactions. They consider factors like mass, speed, and friction to simulate realistic movements. By accurately modeling collision response, developers can enhance player experiences and create immersive environments that mimic real-world physics.
