|

| 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.
