vtk3DWidget

Superclass details

• vtkBoxWidget
  • Class details
  • Orthogonal hexahedron 3D widget
  • It can be used to select, cut, clip, or perform any other operation that depends on an implicit function or it can be used to transform objects using a linear transformation.

• vtkImageTracerWidget
  • Class details
  • 3D widget for tracing on planar props.

• vtkLineWidget
  • Class details
  • This 3D widget defines a line that can be interactively placed in a scene.

• vtkPointWidget
  • Class details
  • This 3D widget allows the user to position a point in 3D space using a 3D cursor.

• vtkPolyDataSourceWidget
  • Class details
  • This abstract class serves as parent to 3D widgets that have simple vtkPolyDataSource instances defining their geometry.

• vtkSphereWidget
  • Class details
  • This 3D widget defines a sphere that can be interactively placed in a scene.

• vtkSplineWidget
  • Class details
  • This 3D widget defines a spline that can be interactively placed in a scene.

vtkAbstractWidget

Superclass details

• vtkAffineWidget
  • Class details
  • The vtkAffineWidget is used to perform affine transformations on objects. (Affine transformations are transformations that keep parallel lines parallel. Affine transformations include translation, scaling, rotation, and shearing.)

• vtkAngleWidget
  • Class details
  • The vtkAngleWidget is used to measure the angle between two rays (defined by three points).

• vtkBiDimensionalWidget
  • Class details
  • The vtkBiDimensionalWidget is used to measure the bi-dimensional length of an object. The bi-dimensional measure is defined by two finite, orthogonal lines that intersect within the finite extent of both lines. The lengths of these two lines gives the bi-dimensional measure. Each line is defined by two handle widgets at the end points of each line.

• vtkBorderWidget
  • Class details
  • This class is a superclass for 2D widgets that may require a rectangular border.

• vtkCheckerboardWidget
  • Class details
  • The vtkCheckerboardWidget is used to interactively control an instance of vtkImageCheckerboard (and an associated vtkImageActor used to display the checkerboard).

• vtkContourWidget
  • Class details
  • The vtkContourWidget is used to select a set of points, and draw lines between these points. The contour may be opened or closed, depending on how the last point is added.

• vtkDistanceWidget
  • Class details
  • The vtkDistanceWidget is used to measure the distance between two points.

• vtkHandleWidget
  • Class details
  • The vtkHandleWidget is used to position a handle. A handle is a widget with a position (in display and world space).

• vtkHoverWidget
  • Class details
  • The vtkHoverWidget is used to invoke an event when hovering in a render window.

• vtkImplicitPlaceWidget2
  • Class details
  • This 3D widget defines an infinite plane that can be interactively placed in a scene.

• vtkLineWidget2
  • Class details
  • This 3D widget defines a straight line that can be interactively placed in a scene.

• vtkRectilinearWipeWidget
  • Class details
  • The vtkRectilinearWipeWidget is used to interactively control an instance of vtkImageRectilinearWipe (and an associated vtkImageActor used to display the rectilinear wipe). A rectilinear wipe is a 2x2 checkerboard pattern created by combining two separate images.

• vtkSeedWidget
  • Class details
  • The vtkSeedWidget is used to placed multiple seed points in the scene. The seed points can be used for operations like connectivity, segmentation, and region growing.

• vtkSliderWidget
  • Class details
  • The vtkSliderWidget is used to set a scalar value in an application.
