vtkConstrainedPointHandleRepresentation

Section: Visualization Toolkit Widget Classes

Usage

This class is used to represent a vtkHandleWidget. It represents a position in 3D world coordinates that is constrained to a specified plane. The default look is to draw a white point when this widget is not selected or active, a thin green circle when it is highlighted, and a thicker cyan circle when it is active (being positioned). Defaults can be adjusted - but take care to define cursor geometry that makes sense for this widget. The geometry will be aligned on the constraining plane, with the plane normal aligned with the X axis of the geometry (similar behavior to vtkGlyph3D).

TODO: still need to work on 1) translation when mouse is outside bounding planes 2) size of the widget

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