Hi, These are the OpenGL style transformation matrices for displaying and drawing your computer models. Check the OpenGL user's guide for the ModelView and Projection matrix. = The ModelView contains position and orientation information for the camera = with respect to the marker. The Projection matrix contains the viewing = frustum information that accounts for perspective effects like foreshortening in = the transformation from camera space to image space.
