Drive Behavior

The Drive behavior places you on the "ground" and allows you to move horizontally through the space (i.e., no vertical control). If the scene graph does not contain ground, the ground will be the highest geometry at the view's position x,z. If the scene graph contains ground, and the ground is uneven, the view will move up and down with the ground.

All controls are provided by the mouse. Each mouse button generates a different type of motion while the button is pressed. The distance of the mouse cursor from the center of the canvas3D controls the speed of motion. The behavior of each button is described below with reference to the View coordinate system.

Mouse Button Description
Left Forward, backward, and yaw. Holding the left mouse button down while moving the mouse up and down moves the view forward and backward. Moving the mouse left and right yaws the view around the Y axis.
Right Translate. Holding the right mouse button down while moving the mouse left and right translates the view along the X axis.
