cone |
The cone object
has a circular cross section and tapers to a point. The following statement
will display a cone with the center of its circular base at (5,2,0), pointing
parallel to the x axis with length 12; the wide end of the cone has radius
1:
cone(pos=(5,2,0), axis=(12,0,0),
radius=1)
The cone object has the following attributes and default values, like those for cylinders: pos (0,0,0), x (0), y(0), z(0), axis (1,0,0), length (1), color (1,1,1) which is color.white, red (1), green (1), blue (1), opacity (1), material, and up (0,1,0). As with cylinders, up has only a subtle effect on the 3D appearance of a cone unless a non-smooth material is specified. Additional cone attribute:
radius Radius of the wide end of the cone, default = 1
Note that the pos attribute for cylinder, arrow, cone, and pyramid corresponds to one end of the object, whereas for a box, sphere, or ring it corresponds to the center of the object.
See description of Additional Attributes available for all 3D display objects.
