If the ProjectionNormal is set to Oblique, then this is the oblique plane used to constrain the handle position.

If the ProjectionNormal is set to Oblique, then this is the oblique plane used to constrain the handle position.

The position of the bounding plane from the origin along the normal. The origin and normal are defined in the oblique plane when the ProjectionNormal is oblique. For the X, Y, and Z axes projection normals, the normal is the axis direction, and the origin is (0,0,0).

A collection of plane equations used to bound the position of the point. This is in addition to confining the point to a plane - these constraints are meant to, for example, keep a point within the extent of an image. Using a set of plane equations allows for more complex bounds (such as bounding a point to an oblique reliced image that has hexagonal shape) than a simple extent.

int vtkBoundedPlanePointPlacer::ComputeWorldPosition ( vtkRenderer ren,
double  displayPos[2],
double  worldPos[3],
double  worldOrient[9] 
) [virtual]

Given a renderer and a display position, compute the world position and world orientation for this point. A plane is defined by a combination of the ProjectionNormal, ProjectionOrigin, and ObliquePlane ivars. The display position is projected onto this plane to determine a world position, and the orientation is set to the normal of the plane. If the point cannot project onto the plane or if it falls outside the bounds imposed by the BoundingPlanes, then 0 is returned, otherwise 1 is returned to indicate a valid return position and orientation.

Reimplemented from vtkPointPlacer.

virtual int vtkBoundedPlanePointPlacer::ComputeWorldPosition ( vtkRenderer ren,
double  displayPos[2],
double  refWorldPos[3],
double  worldPos[3],
double  worldOrient[9] 
) [virtual]

Given a renderer, a display position, and a reference world position, compute the new world position and orientation of this point. This method is typically used by the representation to move the point.

Reimplemented from vtkPointPlacer.

Give a world position check if it is valid - does it lie on the plane and within the bounds? Returns 1 if it is valid, 0 otherwise.

Reimplemented from vtkPointPlacer.

int vtkBoundedPlanePointPlacer::ValidateWorldPosition ( double  worldPos[3],
double  worldOrient[9] 
) [virtual]

Given a world position and a world orientation, validate it according to the constraints of the placer.

Reimplemented from vtkPointPlacer.

virtual int vtkBoundedPlanePointPlacer::UpdateWorldPosition ( vtkRenderer ren,
double  worldPos[3],
double  worldOrient[9] 
) [virtual]

If the constraints on this placer are changed, then this method will be called by the representation on each of its points. For this placer, the world position will be converted to a display position, then ComputeWorldPosition will be used to update the point.

Reimplemented from vtkPointPlacer.
