Detailed Description

3D widget for tracing on planar props.

vtkImageTracerWidget is different from other widgets in three distinct ways: 1) any sub-class of vtkProp can be input rather than just vtkProp3D, so that vtkImageActor can be set as the prop and then traced over, 2) the widget fires pick events at the input prop to decide where to move its handles, 3) the widget has 2D glyphs for handles instead of 3D spheres as is done in other sub-classes of vtk3DWidget. This widget is primarily designed for manually tracing over image data. The button actions and key modifiers are as follows for controlling the widget: 1) left button click over the image, hold and drag draws a free hand line. 2) left button click and release erases the widget line, if it exists, and repositions the first handle. 3) middle button click starts a snap drawn line. The line is terminated by clicking the middle button while depressing the ctrl key. 4) when tracing a continuous or snap drawn line, if the last cursor position is within a specified tolerance to the first handle, the widget line will form a closed loop. 5) right button clicking and holding on any handle that is part of a snap drawn line allows handle dragging: existing line segments are updated accordingly. If the path is open and AutoClose is set to On, the path can be closed by repositioning the first and last points over one another. 6) ctrl key + right button down on any handle will erase it: existing snap drawn line segments are updated accordingly. If the line was formed by continuous tracing, the line is deleted leaving one handle. 7) shift key + right button down on any snap drawn line segment will insert a handle at the cursor position. The line segment is split accordingly.

Warning: the input vtkDataSet should be vtkImageData.

Set the projection normal.

The normal in SetProjectionNormal is 0,1,2 for YZ,XZ,XY planes respectively. Since the handles are 2D glyphs, it is necessary to specify a plane on which to generate them, even though ProjectToPlane may be turned off.

inline

Set the projection normal.

The normal in SetProjectionNormal is 0,1,2 for YZ,XZ,XY planes respectively. Since the handles are 2D glyphs, it is necessary to specify a plane on which to generate them, even though ProjectToPlane may be turned off.

void vtkImageTracerWidget::SetProjectionPosition ( double position )

Set the position of the widgets' handles in terms of a plane's position.

e.g., if ProjectionNormal is 0, all of the x-coordinate values of the handles are set to ProjectionPosition. No attempt is made to ensure that the position is within the bounds of either the underlying image data or the prop on which tracing is performed.

virtual double vtkImageTracerWidget::GetProjectionPosition ( )

virtual

Set the position of the widgets' handles in terms of a plane's position.

e.g., if ProjectionNormal is 0, all of the x-coordinate values of the handles are set to ProjectionPosition. No attempt is made to ensure that the position is within the bounds of either the underlying image data or the prop on which tracing is performed.

void vtkImageTracerWidget::SetSnapToImage ( int snap )

Force snapping to image data while tracing.

Default is Off.

virtual int vtkImageTracerWidget::GetSnapToImage ( )

virtual

Force snapping to image data while tracing.

Default is Off.

virtual void vtkImageTracerWidget::SnapToImageOn ( )

virtual

virtual void vtkImageTracerWidget::SetAutoClose ( int )

virtual

In concert with a CaptureRadius value, automatically form a closed path by connecting first to last path points.

Default is Off.

Default is Off.

virtual void vtkImageTracerWidget::SetCaptureRadius ( double )

virtual

Set/Get the capture radius for automatic path closing.

For image data, capture radius should be half the distance between voxel/pixel centers. Default is 1.0

virtual double vtkImageTracerWidget::GetCaptureRadius ( )

virtual

Set/Get the capture radius for automatic path closing.

For image data, capture radius should be half the distance between voxel/pixel centers. Default is 1.0

void vtkImageTracerWidget::GetPath ( vtkPolyData * pd )

Grab the points and lines that define the traced path.

These point values are guaranteed to be up-to-date when either the InteractionEvent or EndInteraction events are invoked. The user provides the vtkPolyData and the points and cells representing the line are added to it.

vtkGlyphSource2D* vtkImageTracerWidget::GetGlyphSource ( )

inline

Get the handles' geometric representation via vtkGlyphSource2D.

Definition at line 217 of file vtkImageTracerWidget.h.

virtual void vtkImageTracerWidget::SetImageSnapType ( int )

virtual

Set/Get the type of snapping to image data: center of a pixel/voxel or nearest point defining a pixel/voxel.

virtual int vtkImageTracerWidget::GetImageSnapType ( )

virtual

Set/Get the type of snapping to image data: center of a pixel/voxel or nearest point defining a pixel/voxel.

void vtkImageTracerWidget::SetHandlePosition	(	int	handle,
		double	xyz[3]
	)

Set/Get the handle position in terms of a zero-based array of handles.

void vtkImageTracerWidget::SetHandlePosition	(	int	handle,
		double	x,
		double	y,
		double	z
	)

Set/Get the handle position in terms of a zero-based array of handles.

void vtkImageTracerWidget::GetHandlePosition	(	int	handle,
		double	xyz[3]
	)
