Public Functions
-
CameraInputHandlerZoom(bool updateEyePositionOnSetRotationPoint = true)
Creates the Ceetron Zoom Navigation handler.
If updateEyePositionOnSetRotationPoint is set to true, the eye position will be updated to keep the distance from eye -> rotation point if we’re doing zoom navigation to avoid distorted views.
-
virtual void wheelEvent(const WheelEvent &theWheelEvent)
Processes the mouse wheel event.
This is typically called from the viewer (platform dependent class derived from cee::vis::Viewer) based on mouse input.
-
virtual void wheelEvent(const WheelEvent &theWheelEvent, const cee::Vec3d &pos)
Processes the mouse wheel event.
This is typically called from the viewer (platform dependent class derived from cee::vis::Viewer) based on mouse input.
This wheel event also takes a position position which is used for the ‘zoom to cursor’ feature. For normal zoom, use the ordinary wheelEvent() function.
