Detailed Description

point placer that forces the placement of points to the nearest voxel center

vtkKWEVoxelAlignedImageActorPointPlacer is a point placer that works on image actors and automatically forces the placement of the point to the nearest voxel center. This is useful when using voxelized editing widgets and you'd like to see the shape be placed exactly over a voxel rather than in between two voxels.

(

)

[static]

Instantiate this class.

Reimplemented from vtkImageActorPointPlacer.

vtkKWEVoxelAlignedImageActorPointPlacer::vtkTypeRevisionMacro	(	vtkKWEVoxelAlignedImageActorPointPlacer	,
		vtkImageActorPointPlacer
	)

Standard methods for instances of this class.

void vtkKWEVoxelAlignedImageActorPointPlacer::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			[virtual]

Standard methods for instances of this class.

Reimplemented from vtkImageActorPointPlacer.

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

Given and renderer and a display position in pixels, find a world position and orientation. In this class an internal vtkBoundedPlanePointPlacer is used to compute the world position and orientation. The internal placer is set to use the plane of the image actor and the bounds of the image actor as the constraints for placing points.

Reimplemented from vtkImageActorPointPlacer.

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

This method is identical to the one above since the reference position is ignored by the bounded plane point placer.

Reimplemented from vtkImageActorPointPlacer.

int vtkKWEVoxelAlignedImageActorPointPlacer::ValidateWorldPosition

(

double

worldPos[3]

)

[virtual]

This method validates a world position by checking to see if the world position is valid according to the constraints of the internal placer (essentially - is this world position on the image?)

Reimplemented from vtkImageActorPointPlacer.

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

This method is identical to the one above since the bounded plane point placer ignores orientation

Reimplemented from vtkImageActorPointPlacer.

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

Update the world position and orientation according the the current constraints of the placer. Will be called by the representation when it notices that this placer has been modified.

Reimplemented from vtkImageActorPointPlacer.
