Detailed Description

represent 2D affine transformations

This class is used to represent a vtkAffineWidget. This representation consists of three parts: a box, a circle, and a cross. The box is used for scaling and shearing, the circle for rotation, and the cross for translation. These parts are drawn in the overlay plane and maintain a constant size (width and height) specified in terms of normalized viewport coordinates.

The representation maintains an internal transformation matrix (see superclass' GetTransform() method). The transformations generated by this widget assume that the representation lies in the x-y plane. If this is not the case, the user is responsible for transforming this representation's matrix into the correct coordinate space (by judicious matrix multiplication). Note that the transformation matrix returned by GetTransform() is relative to the last PlaceWidget() invocation. (The PlaceWidget() sets the origin around which rotation and scaling occurs; the origin is the center point of the bounding box provided.)

static vtkAffineRepresentation2D* vtkAffineRepresentation2D::New ( )

static

Instantiate this class.

◆ IsTypeOf()

static int vtkAffineRepresentation2D::IsTypeOf ( const char * type )

static

◆ IsA()

virtual int vtkAffineRepresentation2D::IsA ( const char * name )

virtual

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.

Reimplemented from vtkAffineRepresentation.

◆ SafeDownCast()

static vtkAffineRepresentation2D* vtkAffineRepresentation2D::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkAffineRepresentation2D::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkAffineRepresentation.

◆ NewInstance()

vtkAffineRepresentation2D* vtkAffineRepresentation2D::NewInstance ( ) const

◆ PrintSelf()

void vtkAffineRepresentation2D::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

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 vtkAffineRepresentation.

◆ SetBoxWidth()

virtual void vtkAffineRepresentation2D::SetBoxWidth ( int )

virtual

Specify the width of the various parts of the representation (in pixels). The three parts are of the representation are the translation axes, the rotation circle, and the scale/shear box. Note that since the widget resizes itself so that the width and height are always the same, only the width needs to be specified.

◆ SetCircleWidth()

◆ GetAxesWidth()

virtual

◆ SetOrigin() [1/2]

void vtkAffineRepresentation2D::SetOrigin ( const double o[3] )

inline

Specify the origin of the widget (in world coordinates). The origin is the point where the widget places itself. Note that rotations and scaling occurs around the origin.

Definition at line 94 of file vtkAffineRepresentation2D.h.

◆ SetOrigin() [2/2]

void vtkAffineRepresentation2D::SetOrigin	(	double	ox,
		double	oy,
		double	oz
	)

◆ GetOrigin() [1/3]

virtual double* vtkAffineRepresentation2D::GetOrigin ( )

virtual

◆ GetOrigin() [2/3]

virtual void vtkAffineRepresentation2D::GetOrigin	(	double &	,
		double &	,
		double &
	)

virtual

◆ GetOrigin() [3/3]

virtual void vtkAffineRepresentation2D::GetOrigin ( double [3] )

virtual

◆ GetTransform()

virtual void vtkAffineRepresentation2D::GetTransform ( vtkTransform * t )

virtual

Retrieve a linear transform characterizing the affine transformation generated by this widget. This method copies its internal transform into the transform provided. Note that the PlaceWidget() method initializes the internal matrix to identity. All subsequent widget operations (i.e., scale, translate, rotate, shear) are concatenated with the internal transform.

Implements vtkAffineRepresentation.

◆ SetProperty()

void vtkAffineRepresentation2D::SetProperty ( vtkProperty2D * )

Set/Get the properties when unselected and selected.

◆ SetSelectedProperty()

void vtkAffineRepresentation2D::SetSelectedProperty ( vtkProperty2D * )

◆ SetTextProperty()

◆ GetTextProperty()

virtual vtkTextProperty* vtkAffineRepresentation2D::GetTextProperty ( )

virtual

◆ SetDisplayText()

virtual void vtkAffineRepresentation2D::SetDisplayText ( int )

virtual

Enable the display of text with numeric values characterizing the transformation. Rotation and shear are expressed in degrees; translation the distance in world coordinates; and scale normalized (sx,sy) values.

◆ GetDisplayText()

virtual int vtkAffineRepresentation2D::GetDisplayText ( )

virtual

◆ DisplayTextOn()

virtual void vtkAffineRepresentation2D::DisplayTextOn ( )

virtual

◆ DisplayTextOff()

virtual void vtkAffineRepresentation2D::DisplayTextOff ( )

virtual

◆ PlaceWidget()

virtual void vtkAffineRepresentation2D::PlaceWidget ( double bounds[6] )

virtual

Subclasses of vtkAffineRepresentation2D must implement these methods. These are the methods that the widget and its representation use to communicate with each other. Note: PlaceWidget() reinitializes the transformation matrix (i.e., sets it to identity). It also sets the origin for scaling and rotation.

◆ StartWidgetInteraction()

virtual void vtkAffineRepresentation2D::StartWidgetInteraction ( double eventPos[2] )

virtual

Reimplemented from vtkWidgetRepresentation.

◆ WidgetInteraction()

virtual void vtkAffineRepresentation2D::WidgetInteraction ( double eventPos[2] )

virtual

Reimplemented from vtkWidgetRepresentation.

◆ ComputeInteractionState()

virtual int vtkAffineRepresentation2D::ComputeInteractionState	(	int	X,
		int	Y,
		int	modify = `0`
	)

virtual

Reimplemented from vtkWidgetRepresentation.

◆ BuildRepresentation()

virtual void vtkAffineRepresentation2D::BuildRepresentation ( )

virtual

Implements vtkWidgetRepresentation.

◆ ShallowCopy()

virtual void vtkAffineRepresentation2D::ShallowCopy ( vtkProp * prop )

virtual

Methods to make this class behave as a vtkProp.

Reimplemented from vtkAffineRepresentation.

virtual void vtkAffineRepresentation2D::GetActors2D ( vtkPropCollection * )

virtual

Reimplemented from vtkWidgetRepresentation.
