Algosim documentation: sphere


Creates a new sphere.



sphere(a, r) creates a sphere of radius r centred at a.

If omitted, a defaults to ❨0, 0, 0❩ and r to 1.

Consequently, sphere(a, r) is equivalent to ellipsoid(a, ❨r, r, r❩).

The object is shown in the current scene and a reference to the object is returned.

The AdjustVisual function can be used to adjust the appearance of the sphere. See Visual settings for a list of applicable settings.
