Abstract
A method, device and computer system for creating a smooth, continuous height (scalar or vector) field are described. The described techniques permit arbitrary closed regions to be smoothly shaded without producing unnatural smoothness at the region's edges or boundaries.
Claims24
A method of applying an effect to a collection of graphic elements, comprising the steps of:
- a. defining a collection of graphic elements and a specified result criteria;
- b. defining a set of forced values for a first subset of said collection of graphics elements;
- c. applying said set of forced values to said first subset of graphics elements;
- d. applying a filter to a second subset of graphic elements, said second subset of graphic elements characterized by inclusion in said collection of graphic elements but not in said first subset;
- e. testing one or more filtered graphics elements from said second subset to determine if said specified result criteria has been met;
- f. if said specified result criteria has been met, displaying graphic elements derived from said filtered graphics elements of said second subset;
- and
- g. if said specified result criteria has not been met, repeating the process steps d through f.

A method of applying an effect to a finite collection of graphic elements, comprising the steps of:
- a. defining a result criteria;
- b. defining a collection of graphic elements, each of said collection of graphics elements capable of description through identifying an inside region, an outside region, and a boundary at least partially between said inside region and said outside region;
- c. applying a set of forced values to said collection of graphics elements describable as said outside region;
- d. applying a filter to said collection of graphic elements describable as said inside region;
- e. testing one or more filtered graphics elements, from said collection of graphics elements, to determine if said result criteria has been met;
- f. if said result criteria has been met, displaying graphic elements derived from said filtered graphics elements;
- and
- g. if said result criteria has not been met, repeating the process If said specified result criteria has not been met, repeating the process steps d through f.
5 more elements
A method of applying a result effect to graphic elements comprising the steps of:
- a. identifying criteria for indicating whether an effected region of graphics elements sufficiently comprises said result effect;
- b. identifying a value for application to a control region of graphic elements that is at least partially adjacent to said effected region;
- c. applying an operation on a first set of graphic elements, said operation resulting in changes to a group of graphic elements, said group of graphic elements comprising said effected region and said control region;
- d. applying said value to graphic elements in said control region;
- e. testing one or more graphic elements in said effected region to determine if said criteria has been met;
- and
- f. if said criteria has not been met, repeating said steps c through f.
