<BR>I think that you are spot on, Ted.<BR> <BR>The quick zoom in/out gives another situation than a figure that moves (probably in a pre-destined direction) in a terrain... it should be possble to have some large-scale averaged mesh like a mipmap that can quickly kick in, when detail is not needed. The latest idea I got is a simple line-contour around neighbouring areas (or a very crude mesh) signifying that they have been loaded in the background [there are time for that when user watches] and can be clicked to be activated in detail. The image that Michael refers to is faceted .. I prefer it this way becourse a model should not be confused with a reality. The same can be said about the tiled approach above.<BR> <BR>Carsten<BR> <BR> <BR> <BR>Ted said:<BR> <BR><BR>                                            </body>
