Physics Engine

Rigid cuboid simulation and rendering using Rust and WGSL.

Features

• Freely adjustable first-person camera.
• Efficient broad-phase collision detection using spatial hashing.
• Collision manifold calculation using Sutherland-Hodgman face clipping.
• Simple per-face directional lighting with Lambertian diffuse and Blinn-Phong specular highlights.
• Iterative impulse solver that respects conservation of momentum.
• Rotation changes calculated using quaternions to avoid gimbal lock.
