title: Sphere
order: 2
---

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.
