Detailed Description

annotate the render window with scale and distance information

This class is used to annotate the render window. Its basic goal is to provide an indication of the scale of the scene. Four axes surrounding the render window indicate (in a variety of ways) the scale of what the camera is viewing. An option also exists for displaying a scale legend.

The axes can be programmed either to display distance scales or x-y coordinate values. By default, the scales display a distance. However, if you know that the view is down the z-axis, the scales can be programmed to display x-y coordinate values.

Warning:: Please be aware that the axes and scale values are subject to perspective effects. The distances are computed in the focal plane of the camera. When there are large view angles (i.e., perspective projection), the computed distances may provide users the wrong sense of scale. These effects are not present when parallel projection is enabled.

virtual void vtkLegendScaleActor::SetLabelMode ( int ) [virtual]

Specify the mode for labeling the scale axes. By default, the axes are labeled with the distance between points (centered at a distance of 0.0). Alternatively if you know that the view is down the z-axis; the axes can be labeled with x-y coordinate values.

virtual int vtkLegendScaleActor::GetLabelMode ( ) [virtual]

Specify the mode for labeling the scale axes. By default, the axes are labeled with the distance between points (centered at a distance of 0.0). Alternatively if you know that the view is down the z-axis; the axes can be labeled with x-y coordinate values.

void vtkLegendScaleActor::SetLabelModeToDistance ( ) [inline]

Specify the mode for labeling the scale axes. By default, the axes are labeled with the distance between points (centered at a distance of 0.0). Alternatively if you know that the view is down the z-axis; the axes can be labeled with x-y coordinate values.
