Abstract
The invention provides a method for integrating an inset geometry within a background geometry. The method comprises the step of identifying a perimeter of the inset geometry. A further step is extending a skirt, having an outer perimeter and an inner perimeter, from the perimeter of the inset geometry out over the background geometry. An additional step is removing portions of the background geometry that are covered by the inset geometry and skirt. Another step is modifying the skirt so that the outer perimeter of the skirt matches background geometry behavior and the inner perimeter matches inset geometry behavior and a continuous transition exists between the outer perimeter and the inner perimeter.

19. A method for inserting an inset terrain within a larger scale terrain for a computer simulated environment, comprising:
-
determining a perimeter geometry of the inset terrain during runtime;
defining a polygon skirt of substantially the same geometry as the perimeter geometry of the inset terrain and the polygon skirt is attached to the larger scale terrain;
joining the inset terrain to the defined polygon skirt yielding a perimeter boundary region between the inset terrain and the polygon skirt;
arranging a plurality of polygons on the side of the perimeter boundary region that is not intended to be viewed, to prevent gaps from being exposed during display; and
displaying the inset terrain within the larger scale terrain. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
