DESCRIPTION

46       SbCylinderSheetProjector projects a window space point  (usually  based
47       on the mouse location) onto the surface of a cylinder with a hyperbolic
48       sheet draped over it. This allows smooth transitions onto  and  off  of
49       the  cylinder.   Two  projected points can produce a rotation along the
50       cylinder's axis. When the mouse position projects on to the sheet,  the
51       rotations  will be as if the sheet is being dragged, causing the cylin‐
52       der to roll beneath it.
53
54       Incremental changes (delta rotation) can be computed during interactive
55       sessions.  Cylinder  projectors are typically used to write interactive
56       3D manipulators and viewers.

METHODS

59                         SbCylinderSheetProjector(SbBool orientToEye = TRUE)
60                         SbCylinderSheetProjector(const    SbCylinder    &cyl,
61                              SbBool orientToEye = TRUE)
62          Constructors.  The  first uses a default cylinder aligned with the Y
63          axis with radius 1.0; the cylinder is supplied in  the  second.  The
64          orientToEye  parameter determines whether the sheet is perpendicular
65          to the eye, or perpendicular to the cylinder's Z axis. Setting  that
66          parameter  to TRUE (the default) specifies that the plane be perpen‐
67          dicular to the eye, which is most often the desired behavior.
68
69          The default view volume is undefined, and the working space is iden‐
70          tity.
71
72                         ~SbCylinderSheetProjector()
73          Destructor.
