void VRS::PanGroundPlateNavigation::setMinDragAngle

(

double

degrees = 10.0

)

Dragging points is only useful if you look from above at a certain minimum slope.

Therefore, drag points are only considered if the ray passing from the camera to the drag point points downwards and forms at least a certain angle with the horizontal plane.

const

virtual bool VRS::PanGroundPlateNavigation::preservingViewDirectionRequired

(

)

const [virtual]

Used to determine whether the view direction must be preserved after a constraintchecker has refused or corrected a movement of this technique.

By default, the method returns always 'false'. It must be overloaded, and return 'true' to force preserving of the view direction.

Reimplemented from VRS::InteractionTechnique.
