The units arenormalized to the scene.For example, setting dx to 1 moves the camera to the right, which pushes thescene to the left edge of the box formed by the axes position rectangle. Anegative value moves the scene in the other direction. Setting dz to 0.5moves the camera to a position halfway between the camera position and thecamera target• pixels – interpret dx and dy as pixel offsets. dz is ignored.• data – interpret dx, dy, and dz as offesets in axes data coordinates.camdolly(axes_handle,...) operates on the axes identified by the firstargument, axes_handle. When you do not specify an axes handle, camdollyoperates on the current axes.2-51
