Ellipsoids

3D ellipsoids or spheres.

This archetype is for ellipsoids or spheres whose size is a key part of the data (e.g. a bounding sphere). For points whose radii are for the sake of visualization, use archetypes.Points3D instead.

Currently, ellipsoids are always rendered as wireframes. Opaque and transparent rendering will be supported later.
