37 // Class description:
38 //
39 // This class implements a tube with hyperbolic profile.
40 //
41 // It describes an hyperbolic volume with curved sides parallel to
42 // the z-axis. The solid has a specified half-length along the z axis,
43 // about which it is centered, and a given minimum and maximum radius.
44 // A minimum radius of 0 signifies a filled Hype (with hyperbolical
45 // inner surface). To have a filled Hype the user must specify
46 // inner radius = 0 AND inner stereo angle = 0.
47 //
48 // The inner and outer hyperbolical surfaces can have different
49 // stereo angles. A stereo angle of 0 gives a cylindrical surface.
