# The sphere Object

Here is an example of how to make a sphere:

## ball = sphere(pos=(1,2,1), radius=0.5)

This produces a sphere centered at location (1,2,1) with radius = 0.5, with the current foreground color.

The sphere object has the following attributes and default values, like those for cylinders except that there is no length attribute: pos (0,0,0), x (0), y(0), z(0), axis (1,0,0), color (1,1,1) which is color.white, red (1), green (1), blue (1), and up (0,1,0). As with cylinders, up has a subtle effect on the 3D appearance of a sphere. The axis attribute only affects the orientation of the sphere and has a subtle effect on appearance; the magnitude of the axis attribute is irrelevant. Additional sphere attributes:

radius Radius of the sphere, default = 1

Note that the pos attribute for cylinder, arrow, cone, and pyramid corresponds to one end of the object, whereas for a sphere it corresponds to the center of the object.

Originally there was a label attribute for the sphere object, but this has been superceded by the label object.
