| 39 | // |
---|
| 40 | // This class implements a tube with hyperbolic profile. |
---|
| 41 | // |
---|
| 42 | // It describes an hyperbolic volume with curved sides parallel to |
---|
| 43 | // the z-axis. The solid has a specified half-length along the z axis, |
---|
| 44 | // about which it is centered, and a given minimum and maximum radius. |
---|
| 45 | // A minimum radius of 0 signifies a filled Hype (with hyperbolical |
---|
| 46 | // inner surface). To have a filled Hype the user must specify |
---|
| 47 | // inner radius = 0 AND inner stereo angle = 0. |
---|
| 48 | // |
---|
| 49 | // The inner and outer hyperbolical surfaces can have different |
---|
| 50 | // stereo angles. A stereo angle of 0 gives a cylindrical surface. |
