Documentation

-HoverManipulator is a MatrixManipulator which provides a camera motion model using mouse and keyboard, -designed for flythrough applications (eg. architectural visualisation). -This class was based on FlightManipulator and inspired by the OpenGL Performer (TM) 'fly' navigation mode. - -
Mouse input: -Dragging the middle mouse button changes the orientation of the camera. -While holding down the middle mouse button, you increase/decrease flying speed using the left and -right mouse buttons. Pressing the left and right buttons simultaneously works as a brake. - -
Keyboard input: -Space - stops all motion immediately -Arrow keys - move the camera parallel to the ground plane. Holding two 'opposing' arrow keys works as a -brake. -'r' or 'R' - return the camera to the 'home' position ------- -Martijn Kragtwijk, May 2004
