helix

The following statement will display a helix that is parallel to the x axis:

spring = helix(pos=(0,2,1), axis=(5,0,0), radius=0.5)

The helix object has the following attributes and default values: pos (0,0,0), x (0), y(0), z(0), axis (1,0,0), length (1), radius (1), coils (5), thickness (radius/20), color (1,1,1) which is color.white, red (1), green (1), blue (1), material, and up (0,1,0)

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

Currently it is not possible to specify the opacity of a helix object, which is based on the curve object.

See description of Additional Attributes available for all 3D display objects.
