Sphere

A perfect sphere, smooth at any scale, no subdivision needed. The clearest demonstration of why SDFs beat meshes: zoom in as far as you like and the silhouette stays exact.

Parameters

• Radius: distance from center to surface (default 1.0, soft max 10.0)

Notes

No rounding parameter: the sphere is already perfectly smooth. Non-uniform object scale stretches it into an ellipsoid.
