Detailed Description

Interactor for Affine transformations on one or multiple surfaces.

A surface interacted by this class can translate, rotate and scale by modifying its geometry. The surface closest to the picking point is chosen for interaction automatically by CanHandleEvent

Member Function Documentation

float mitk::SurfaceInteractor::CanHandleEvent

(

StateEvent const *

stateEvent )

const [protected, virtual]

calculates how good the data this state machine handles is hit by the event.

Returns a value between 0 and 1. (Used by GlobalInteraction to decide which DESELECTED state machine to send the event to.)

This is interactor currently does not work for interaction in 3D. Try using mitkAffineInteractor3D instead.

Reimplemented from mitk::AffineInteractor.
