Remarks

OIV.Inventor.Draggers.SoEllipsoidDragger is derived from OIV.Inventor.Draggers.SoTabPlaneDragger and has similar behavior. The difference is that the displayed shape is an ellipsoid that fills the extent of the dragger.

If you set the OIV.Inventor.Draggers.SoEllipsoidDragger.constrained field to true, the edge tabs are hidden (only corner tabs are visible) and scaling is uniform.

The OIV.Inventor.Draggers.SoEllipsoidDragger.numSamples field specifies the number of points used to draw the ellipsoid. You can ensure the displayed shape is a circle if you set the OIV.Inventor.Draggers.SoEllipsoidDragger.constrained field to true before any scaling is applied.

The scaleUniform and lineWidth fields inherited from OIV.Inventor.Draggers.SoTabPlaneDragger are ignored.

See OIV.Inventor.Draggers.SoDragger for more information about using and customizing draggers, including code examples, using draggers in an immersive VR environment and using WYSIWYG draggers.
