Detailed Description

The SbSphereSheetProjector class projects 2D points to 3D points on a sheet covering a spherical shape.

---

Constructor & Destructor Documentation

SbSphereSheetProjector::SbSphereSheetProjector (  const SbBool orienttoeye = TRUE )

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

SbSphereSheetProjector::SbSphereSheetProjector (  const SbSphere & sph, const SbBool orienttoeye = TRUE )

Constructor with explicit definition of projection sphere.

---

Member Function Documentation

SbProjector * SbSphereSheetProjector::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 SbSphereSheetProjector::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 SbProjector.

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

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

void SbSphereSheetProjector::setupPlane (  void )  [protected]

Recalculates projection surface settings after changes to the parameters.

---

Member Data Documentation

SbSphereSheetProjector::workingProjPoint [protected]

Last projected point, in the working space coordinate system.

SbSphereSheetProjector::planePoint [protected]

Position of the center of the sphere in the plane of the hyberbolic sheet.

SbSphereSheetProjector::planeDir [protected]

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

SbSphereSheetProjector::planeDist [protected]

For internal use only.

SbSphereSheetProjector::tolPlane [protected]

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