概述
A cylinder is represented by its location, axis vector, and radius. The
reference vector need not be perpendicular to the axis, but must not
be parallel to it. Parameterization is 0 to 2pi in u and by length in
part units along the axis in v, positive in the direction of the axis
vector.


Data Members

pt_on_axis [ 3 ]
double

defines zero v.

axis [ 3 ]
double
The axis vector for the cylinder.

u0_ref_direc [ 3 ]
double
Reference direction which defines the
orientation of zero u.

radius
double
The radius of the cylinder.
