Embodiment Construction

[0022] Reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated herein, and additional applications of the principles of the inventions as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

[0023] In the past, computer graphics modeling has not included the ability to dynamically incorporate geometry elements at run-time into background geometry or a global geometry. One problem to be overcome in order to directly incorporate an additional piece of geometry into the background geometry is that the inset geometry needs to know specific things about the background geometry in order to be arranged, c...

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.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to computer graphics. More particularly, the present invention relates to run-time integration of an inset geometry into a background geometry. BACKGROUND [0002] Computers have been used for many years to do image and graphics generation. In recent years computer generated graphics have become more sophisticated and the power of computer equipment has increased. Similarly, users' expectations of computer graphics have also increased. Computer users have come to expect more realism in computer graphics which generally means that there are more objects, and more light and texture processing on those objects. [0003] Complex images and scenes are mathematically modeled in a three-dimensional space in the computer memory and manipulated accordingly. These three-dimensional mathematical models are called wire frames because all the edges of the object are visible at the same time when displayed. Three-dimensional models...
