Octahedral Impostors
WebGPU direction-atlas impostors for cheap distant meshes · 2026 · Components, WebGPU, Experiments
A visual WebGPU demo of octahedral impostors — bake a mesh into a direction atlas, then draw cheap billboard cards that pick and blend the right atlas cells as the camera moves.
Built with React Three Fiber, Three.js WebGPU and TSL: hemisphere grids, live atlas sampling, barycentric blends and a field of impostors you can scale from a handful to hundreds — inspired by the Shaderbits octahedral impostors approach.
The demo, reusable component and source will be available soon, after the Three.js Conference Paris.
