Detailed Description

The SbCylinderSheetProjector class projects 2D points to 3D points on a sheet covering a cylindrical shape.

---

Constructor & Destructor Documentation

SbCylinderSheetProjector::SbCylinderSheetProjector (  const SbBool orienttoeye = TRUE )

Constructor. Uses default cylinder defintion, see SbCylinderProjector::SbCylinderProjector(). orienttoeye decides whether or not the cylinder and sheet should always be oriented towards the viewer.

SbCylinderSheetProjector::SbCylinderSheetProjector (  const SbCylinder & cyl, const SbBool orienttoeye = TRUE )

Constructor with explicit definition of projection cylinder.

---

Member Function Documentation

SbProjector * SbCylinderSheetProjector::copy (  void )  const [virtual]

Construct and return a copy of this projector. The caller is responsible for destructing the new instance. Reimplemented from SbProjector.

SbVec3f SbCylinderSheetProjector::project (  const SbVec2f & point )  [virtual]

Project the 2D point from normalized viewport coordinates to a 3D point. The mapping will be done in accordance with the type of the projector. Reimplemented from SbCylinderProjector.

SbRotation SbCylinderSheetProjector::getRotation (  const SbVec3f & point1, const SbVec3f & point2 )  [virtual]

Returns rotation on the projection surface which re-orients point1 to point2. Reimplemented from SbCylinderProjector.

void SbCylinderSheetProjector::setupPlane (  void )  [protected, virtual]

Recalculates projection surface settings after changes to the parameters.

---

Member Data Documentation

SbCylinderSheetProjector::workingProjPoint [protected]

Last projected point, in the working space coordinate system.

SbCylinderSheetProjector::planeDir [protected]

Normal vector of the plane defining the orientation of the sheet.

SbCylinderSheetProjector::tolPlane [protected]

The tolerance value specifying how much of the cylinder is "above" the sheet.
