Does Unity support spheres that are not meshes but mathematically defined?

I don’t think it does but I thought I would ask.

I’d like to define thousands of small spheres by their center point, radius, and material. Is that possible in Unity?

Would that even be more efficient than a modern GPU rendering a mesh sphere?

I suppose you could make some kind of NURBS code but at the end of the day it will be tesselated (turned into geometry) and then rasterized like anything else.

It certainly wouldn’t be faster than just putting enough geometry in.

The only thing approaching a “mathematically defined” sphere would be the SphereCollider object, which is invisible.
