Could you build this?
Partial The browser game UI and PlayCanvas scene setup are vibe-codeable, but converting unstructured 3D Gaussian Splats into physical colliders and navigational meshes requires specialized graphics processing pipelines.
What it would actually take: Building this requires extracting surface geometry approximations from raw 3D Gaussian Splat point distributions using Poisson surface reconstruction or alpha shapes to generate rigid collision meshes and recast navmeshes. The developer needs specialized expertise in computer graphics, WebGPU compute shaders, and spatial geometric reconstruction algorithms.
Discussion
20 comments analyzed.
Competitors mentioned: World Labs/Marble for world modeling, Gaussian Tracer (splats with raytracing), Cyberpunk 2077
Concerns raised: View model looks uncanny compared to environment, Mobile browser performance poor on lower-end devices (screen distortion crash), Requires dozens of cameras/drones for 4D outdoor scanning, High barrier to entry for professional 3D capture (expensive equipment, artist time)
Feature requests: Permissive license for view model/hands assets, Better mobile optimization/streaming LOD tuning
