Detailed DescriptionThe 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​. Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make sure that both the Coin DLL and the application executable is using the same instance of a C Run-Time (CRT) library​. Otherwise, you will get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes​.

Implements 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​. Implements SbCylinderProjector​.

---

SbRotation SbCylinderSheetProjector::getRotation (const SbVec3f & point1, const SbVec3f & point2) [virtual]Returns rotation on the projection surface which re-orients point1 to point2​. Implements 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​.
