DESCRIPTIONSbCylinderSheetProjector 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.
FUNCTIONSSbCylinderSheetProjector * SbCylSheetProjCreate(SbBool orientToEye =
TRUE)
SbCylinderSheetProjector * SbCylSheetProjCreateCyl(const SbCylinder
*cyl, SbBool orientToEye = TRUE)
Constructors. The first uses a default cylinder aligned with the Y
axis with radius 1.0; the cylinder is supplied in the second. 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.
void SbCylSheetProjDelete(SbCylSheetProj *this)
Destructor.
