Soft body physics is a simulation technique used in computer graphics and game development to model the behavior of flexible and deformable objects. Unlike rigid bodies, which maintain their shape, soft bodies can bend, stretch, and compress, allowing for more realistic interactions with their environment. This is particularly useful for simulating materials like rubber, cloth, or jelly. In soft body physics, algorithms calculate how forces affect the shape and movement of these objects. Techniques such as mass-spring models and finite element methods are commonly employed to achieve realistic results. This technology enhances visual realism in applications ranging from animated films to video games, making interactions more engaging and believable.
