MeshFactory builds the small primitive geometries used throughout disp3D — subdivided icosahedron spheres for source-space and digitizer points, oriented plates for MEG magnetometers, barbell shapes for gradiometers, cylinders for sensor leads and connectivity edges. Each primitive is returned as a fully populated BrainSurface with interleaved position / normal / colour vertex data so it drops straight into the standard render pipeline.

For point clouds (source-space, head-shape digitization), all spheres are merged into a single BrainSurface so the GPU draws thousands of points with one drawIndexed call — this is the same single-draw constraint imposed by the WebGL backend that the rest of disp3D obeys.
