In Unreal Engine 4 we wanted to make binding input events as easy as possible. To that end, we created Input Action and Axis Mappings. While it is certainly valid to bind keys directly to events, I hope I can convince you that using mappings will be the most flexible and convenient way to set up your input.

From vtk vtkInteractorStyle ClassReference:. Keypress j / Keypress t: toggle betweenjoystick (position sensitive) and trackball (motion sensitive) styles. Injoystick style, motion occurs continuously as long as a mouse button ispressed. In trackball style, motion occurs when the mouse button is pressedand the mouse pointer moves. Keypress c / Keypress a: toggle betweencamera and actor modes. In camera mode, mouse events affect the cameraposition and focal point.

In actor mode, mouse events affect the actor that isunder the mouse pointer. Button 1: rotate the camera around itsfocal point (if camera mode) or rotate the actor around its origin (if actormode). The rotation is in the direction defined from the center of therenderer's viewport towards the mouse position. In joystick mode, themagnitude of the rotation is determined by the distance the mouse is from thecenter of the render window. Button 2: pan the camera (if camera mode)or translate the actor (if actor mode).

In joystick mode, the direction of panor translation is from the center of the viewport towards the mouse position.In trackball mode, the direction of motion is the direction the mouse moves.(Note: with 2-button mice, pan is defined as -Button 1.). Button 3: zoom the camera (if camera mode)or scale the actor (if actor mode). Zoom in/increase scale if the mouseposition is in the top half of the viewport; zoom out/decrease scale if themouse position is in the bottom half. In joystick mode, the amount of zoom iscontrolled by the distance of the mouse pointer from the horizontal centerlineof the window. Keypress 3: toggle the render window intoand out of stereo mode. By default, red-blue stereo pairs are created. Somesystems support Crystal Eyes LCD stereo glasses; you have to invokeSetStereoTypeToCrystalEyes on the rendering window.

Keypress e: exit the application. Keypress f: fly to the picked point. Keypress p: perform a pick operation. Therender window interactor has an internal instance of vtkCellPicker that it uses to pick. Keypress r: reset the camera view along thecurrent view direction. Centers the actors and moves the camera so that allactors are visible.

Keypress s: modify the representation ofall actors so that they are surfaces. Keypress u: invoke the user-definedfunction. Typically, this keypress will bring up an interactor that you cantype commands in. Keypress w: modify the representation ofall actors so that they are wireframe.
