vtkCompassRepresentation

Section: Visualization Toolkit Geo Vis Classes

# Usage

This class is used to represent and render a compass.

To create an instance of class vtkCompassRepresentation, simply invoke its constructor as follows

      obj = vtkCompassRepresentation

# Methods

The class vtkCompassRepresentation has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkCompassRepresentation class.

- `string = obj.GetClassName ()` - Standard methods for the class.
- `int = obj.IsA (string name)` - Standard methods for the class.
- `vtkCompassRepresentation = obj.NewInstance ()` - Standard methods for the class.
- `vtkCompassRepresentation = obj.SafeDownCast (vtkObject o)` - Standard methods for the class.
- `vtkCoordinate = obj.GetPoint1Coordinate ()` - Position the first end point of the slider. Note that this point is an instance of vtkCoordinate, meaning that Point 1 can be specified in a variety of coordinate systems, and can even be relative to another point. To set the point, you'll want to get the Point1Coordinate and then invoke the necessary methods to put it into the correct coordinate system and set the correct initial value.
- `vtkCoordinate = obj.GetPoint2Coordinate ()` - Position the second end point of the slider. Note that this point is an instance of vtkCoordinate, meaning that Point 1 can be specified in a variety of coordinate systems, and can even be relative to another point. To set the point, you'll want to get the Point2Coordinate and then invoke the necessary methods to put it into the correct coordinate system and set the correct initial value.
- `vtkProperty2D = obj.GetRingProperty ()` - Get the slider properties. The properties of the slider when selected and unselected can be manipulated.
- `vtkProperty2D = obj.GetSelectedProperty ()` - Get the selection property. This property is used to modify the appearance of selected objects (e.g., the slider).
- `vtkTextProperty = obj.GetLabelProperty ()` - Set/Get the properties for the label and title text.
- `obj.PlaceWidget (double bounds[6])` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `obj.BuildRepresentation ()` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `obj.StartWidgetInteraction (double eventPos[2])` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `obj.WidgetInteraction (double eventPos[2])` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `obj.TiltWidgetInteraction (double eventPos[2])` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `obj.DistanceWidgetInteraction (double eventPos[2])` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `int = obj.ComputeInteractionState (int X, int Y, int modify)` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `obj.Highlight (int )` - Methods to interface with the vtkSliderWidget. The PlaceWidget() method assumes that the parameter bounds[6] specifies the location in display space where the widget should be placed.
- `obj.GetActors (vtkPropCollection )`
- `obj.ReleaseGraphicsResources (vtkWindow )`
- `int = obj.RenderOverlay (vtkViewport )`
- `int = obj.RenderOpaqueGeometry (vtkViewport )`
- `obj.SetHeading (double value)`
- `double = obj.GetHeading ()`
- `obj.SetTilt (double value)`
- `double = obj.GetTilt ()`
- `obj.UpdateTilt (double time)`
- `obj.EndTilt ()`
- `obj.SetDistance (double value)`
- `double = obj.GetDistance ()`
- `obj.UpdateDistance (double time)`
- `obj.EndDistance ()`
- `obj.SetRenderer (vtkRenderer ren)`
