Detailed Description

map a slice of a vtkImageData to the screen

vtkImageResliceMapper will cut a 3D image with an abitrary slice plane and draw the results on the screen. The slice can be set to automatically follow the camera, so that the camera controls the slicing.

Thanks:: Thanks to David Gobbi at the Seaman Family MR Centre and Dept. of Clinical Neurosciences, Foothills Medical Centre, Calgary, for providing this class.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

◆ PrintSelf()

void vtkImageResliceMapper::PrintSelf	(	ostream &	os,

	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImageMapper3D.

◆ SetSlicePlane()

virtual void vtkImageResliceMapper::SetSlicePlane ( vtkPlane * plane )

virtual

Set the slice that will be used to cut through the image.

This slice should be in world coordinates, rather than data coordinates. Use SliceFacesCamera and SliceAtFocalPoint if you want the slice to automatically follow the camera.

◆ SetJumpToNearestSlice()

virtual void vtkImageResliceMapper::SetJumpToNearestSlice ( vtkTypeBool )

virtual

When using SliceAtFocalPoint, this causes the slicing to occur at the closest slice to the focal point, instead of the default behavior where a new slice is interpolated between the original slices.

This flag is ignored if the slicing is oblique to the original slices.

◆ JumpToNearestSliceOn()

virtual void vtkImageResliceMapper::JumpToNearestSliceOn ( )

virtual

When using SliceAtFocalPoint, this causes the slicing to occur at the closest slice to the focal point, instead of the default behavior where a new slice is interpolated between the original slices.

This flag is ignored if the slicing is oblique to the original slices.

◆ JumpToNearestSliceOff()

virtual void vtkImageResliceMapper::JumpToNearestSliceOff ( )

virtual

When using SliceAtFocalPoint, this causes the slicing to occur at the closest slice to the focal point, instead of the default behavior where a new slice is interpolated between the original slices.

This flag is ignored if the slicing is oblique to the original slices.

◆ GetJumpToNearestSlice()

virtual vtkTypeBool vtkImageResliceMapper::GetJumpToNearestSlice ( )

virtual

When using SliceAtFocalPoint, this causes the slicing to occur at the closest slice to the focal point, instead of the default behavior where a new slice is interpolated between the original slices.

This flag is ignored if the slicing is oblique to the original slices.

◆ SetSlabThickness()

virtual void vtkImageResliceMapper::SetSlabThickness ( double )

virtual

The slab thickness, for thick slicing (default: zero)
