selfcollisions

Self-collision refers to a situation in computer graphics and animation where a moving object intersects with itself. This phenomenon typically occurs with deformable objects, such as characters' limbs passing through their own bodies or cloth simulations where fabric folds and overlaps unnaturally. In physics simulations, self-collision detection is crucial for maintaining physical realism. When a self-collision is detected, the simulation system needs to resolve the intersection, usually by applying forces or constraints to prevent or correct the overlapping geometry. Without proper handling, self-collisions can lead to visual artifacts, unstable simulations, and incorrect physical behavior. Various algorithms exist to detect and resolve self-collisions, often involving spatial partitioning or bounding volume hierarchies to efficiently check for intersections. The complexity of self-collision detection and resolution can be a significant factor in the performance of real-time rendering and animation systems. Properly managing self-collisions is essential for creating convincing and stable digital representations of the physical world.
