Räsikokkupõrge

Räsikokkupõrge, meaning "ragdoll collision" in Estonian, refers to a specific type of physics simulation in computer graphics and game development. It is characterized by a soft, flexible, and often exaggerated response to physical forces, creating a visual effect where objects or characters appear to bend, stretch, or collapse in a floppy, ragdoll-like manner. Unlike rigid body physics, which treats objects as solid and unyielding, räsikokkupõrge prioritizes a more fluid and less predictable deformation.

This technique is commonly employed to simulate the movement of characters after they have been defeated or knocked down in a video game. When a character is no longer actively controlled, their physics simulation can switch to räsikokkupõrge, allowing their limbs and body to react to gravity and collisions in a way that appears more natural or comically inert. The term itself evokes the image of a cloth doll, whose movements lack internal structure and are governed primarily by external forces and their own weight.

The implementation of räsikokkupõrge often involves a system of interconnected joints and springs, where each joint can rotate and the springs between them provide a degree of elasticity. This allows for a degree of control and fine-tuning, enabling developers to achieve specific visual styles, from slightly wobbly to extremely floppy. While it adds a layer of realism or comedic effect, it also requires careful calibration to avoid overly chaotic or visually jarring results. The term is primarily used within the Estonian-speaking technical communities related to game development and computer animation.
