Option for off-centred sphere.


Option for converting a sphere to an off-centred sphere.


What we mean here by an off-centred sphere is an object created by rotating an arc of a circle around an axis when the centre of the circle is not on the axis.

The offset distance is the distance between the axis and the centre of the circle, and is positive when the arc and its centre are on opposite sides of the axis.

The offset distance would usually be positive and less than the radii of the bounding circles When other values are chosen some interesting shapes are generated.


The option can be activated at the bottom of the edit sheet of a sphere.
