GpuDrivenMesh

One mesh of a GPU-driven scene: its vertices, its clusters, and which material shades it.

Properties

Name	Type	Description
`positions`readonly	`Float32Array`	Three floats a vertex.
`normals`readonly	`Float32Array`	Three floats a vertex.
`colours`readonly	`Float32Array`	Three floats a vertex.
`uvs`readonlyoptional	`Float32Array`	Two floats a vertex. Optional: a mesh without them uploads zeros, and a textured material on it reads one texel everywhere and turns no normal — a statement about the mesh, and what the forward path does with an absent attribute.
`emissive`readonlyoptional	`Float32Array`	One float a vertex, added to the material's own emissive. Optional: a mesh without it glows as its material says and nothing more, which is every mesh before 2026-09-18. More For light a colour cannot carry. The voxel sandbox folds occlusion and sky light into the vertex colour and keeps block light here, because it has to survive the sun going down and a colour is multiplied by the sun. The forward path reads the same attribute from `MeshData`.
`clusters`readonly	`ClusterSource`	This mesh's clusters, with indices addressing this mesh's vertices.
`material`readonly	`number`	Which material bin every cluster of this mesh shades in.
