THREE.JS / FOUNDATIONS / SOURCE PROMOTION

A native node-material sandbox.

The source-shaped lane keeps WebGPURenderer, TSL node graphs, Inspector, KTX2 loading, generated data textures, points, and attribute-driven lines observable.

Asset and fidelity boundary

The official UV-grid and transition images are replaced by deterministic local TextureLoader data URLs; the official UASTC path uses the repo’s local 2d_uastc.ktx2 plus bundled Basis transcoder. Native WebGPU is attempted first; ?forceWebGL=1 is an explicit WebGL2 reference lane.

Exact official example.css/Inspector presentation, 512² data texture, remote image provenance, pixel parity, device/compiler/performance matrices, teardown stress, and whole-example fidelity remain separate.

Derived from the official webgpu_sandbox source at the pinned commit.
