public class SbCylinderSheetProjector
extends SbCylinderProjector
```
Cylinder-sheet projector. SbCylinderSheetProjector projects a window space point (usually based on the mouse location) onto the surface of a cylinder with a hyperbolic sheet draped over it. This allows smooth transitions onto and off of the cylinder. Two projected points can produce a rotation along the cylinder's axis. When the mouse position projects on to the sheet, the rotations will be as if the sheet is being dragged, causing the cylinder to roll beneath it.
Incremental changes (delta rotation) can be computed during interactive sessions. Cylinder projectors are typically used to write interactive 3D manipulators and viewers.

```
public SbCylinderSheetProjector(SbCylinder cyl)
```
    Calls SbCylinderSheetProjector(cyl, true).

```
public SbCylinderSheetProjector()
```
    Calls SbCylinderSheetProjector(true).
  - SbCylinderSheetProjector
```
public SbCylinderSheetProjector(boolean orientToEye)
```
    Constructor that uses a default cylinder aligned with the Y axis with radius 1.0. The orientToEye parameter determines whether the sheet is perpendicular to the eye, or perpendicular to the cylinder's Z axis. Setting that parameter to true (the default) specifies that the plane be perpendicular to the eye, which is most often the desired behavior.
    The default view volume is undefined, and the working space is identity.
