Try it live Description
Skyline Sprint is a browser-based 3D time-trial racing game, made for anyone who wants one more lap. Its course, about 1.13 km long, runs above the clouds between floating islands, with sweeping corners, an island jump and a vertical loop. Pick one of three cars, pass six checkpoints in order and finish the lap as fast as you can.
Gentle drifting leaves tire marks on the road. After a run you can check your split times, chase your personal best and race a ghost car from your previous lap. The game supports keyboard and touch controls, with the interface in Chinese or English.
The world is built with Three.js, and Rapier handles vehicle physics and collisions. Cars, floating islands, airships, buildings, warning signs and barriers were generated with Tripo, then adjusted in Blender for scale, structure and detail. Models, music and sound effects all load before the race begins, so everything is ready when you start. The two panoramas and the basalt texture were made with OpenAI Image Generation, and the two Sky Flight background tracks were generated by the author with Suno.
How Tripo was used
The cars and scenery along this sky-high track were generated with Tripo.
- Track assets: Tripo supplied 3D assets including race cars, floating islands and energy props.
- New models: on top of those, Tripo P1 added an endurance car, a rally car, a warning sign, a barrier, an airship and a sky citadel.
- Refinement and integration: the author refined scale and details in Blender, separated the wheels and integrated the GLB models into Three.js.
- The prompts, seeds and generation receipts are published with the project.
