SkiSim, with a lidar-built Park City

Field notes

The project separates authored courses from geographic reconstruction. Kernel Peak and Mutex Ridge provide measured downhill routes, while the Park City mode is described as streaming terrain from USGS 3DEP lidar and OpenStreetMap across 85.47 km². Its input model includes carving, braking, jumping, aerial spins and flips, grabs, gamepad support, and touch controls. The runtime is described as using WebGPU when available and WebGL2 as a fallback.
