Physics Optimization Guide
Physics optimization is a crucial aspect in game development, computer graphics, and simulations. This guide provides an overview of the key concepts and techniques used in physics optimization.
Key Concepts
- Simulation: The process of simulating real-world physics in a virtual environment.
- Collision Detection: The process of determining if two objects are overlapping or intersecting.
- Rigidbody: A component in physics simulations that represents a physical object with mass, position, and velocity.
- Constraint: A physical connection between two rigidbodies that restricts their relative motion.
Optimization Techniques
- Spatial Partitioning: Techniques such as grids, octrees, and BVHs to efficiently query potential collisions.
- Broad Phase: Determining which objects are likely to collide using spatial partitioning.
- Narrow Phase: Calculating the exact collision points and response between objects.
- Caching: Storing the results of expensive calculations to avoid redundant processing.
- Damping: Reducing the energy of an object to prevent unrealistic motion.
- Simplification: Reducing the number of objects or simplifying their shapes to decrease the computational load.
