public static class SurfaceGeometryTurning a MeshData into the vertices a GeometryBuffer holds.
No guide page documents this yet — the page shows what the code says about itself.
Remarks
The one place that goes from the shape a compiler produces — parallel arrays, some of them empty — to the interleaved SurfaceVertex the shading stages read. It is a pure function of the mesh, which is what lets every question about it be a test with no device in it.
⚠ A missing attribute is filled in rather than refused, and each one is filled in differently because each absence means something different. An empty array says the file did not have it — see MeshData on why that is not the same as an array of zeros — and a mesh with no tangents is the ordinary case rather than a broken one: MeshPrimitives produces none at all.
