controller.TrackballController.TrackballController
A controller that emulates a 'Trackball' behavior.<br> <br> This controller let the user manipulate the camera position using mouse or touch input.<br> <br> This controller uses a 3D anchor point and will revolve around it (named lookAt).<br> This anchor point can be changed either by user action (double click/tap) or programmatically.<br> <br> It will let the user rotate the camera on the 'horizontal' axis infinitely.<br> But it prevents the user from rotate the camera on the vertical axis more than 0-180 degrees.<br> So that the user cannot put the camera upside down.<br> <br> This controller also support 'zooming' by moving the camera forward or backward.<br> <br> To be used, it should be set on the Plot through the setOptions function. <br> Most of the behaviors can be configured either for speed or even to disable some actions through the setOptions. <br>
