Real-time sand simulation & terramechanics in the browser (WebGPU)

• Bekker–Wong sinkage + Mason traction + Pouliquen grain flow
• Real-time tire–soil interaction
• Mass-conserving sand
• Endless procedural open world, dunes checked against lidar
• Zero sand textures, fully procedural sand shading
• - Built from scratch: custom sand sim, vehicle physics & shaders – no game or physics engine
• One build for desktop & mobile
• three.js r187

AI slop experiment, but the driving physics are still better than GTA 6.

WIP

More updates and demo coming soon...
