System and method for smoothing three dimensional images

Abstract

A method and system for converting two-dimensional artwork into three-dimensional models. Data relating to an image is imported and segments of the image are chained into contiguous curves. The contiguous curves together may form loops. Subsets of closed loops are split and created where surfaces of the image are to be created. The closed loops are contoured to create contours. The geometries created are projected onto a surface as an image. Finally, the image is smoothed.

1 . A method of creating a three-dimensional image, comprising:
 importing data relating to a two-dimensional image;   chaining segments of the image into contiguous curves;   forming loops from the contiguous curves;   creating at least one subset of loops;   contouring the at least one subset of loops to form a contoured area;   projecting geometries of the contoured area onto a surface;   smoothing the image.   
     
     
         2 . The method of  claim 1 , wherein the data is a collection of line segments and curves that together form the image. 
     
     
         3 . The method of  claim 1 , wherein the chaining of segments into contiguous curves is done by finding matching endpoints and constructing chains using the endpoints. 
     
     
         4 . The method of  claim 1 , further comprising repeating connecting segments to reduce the number of contiguous curves. 
     
     
         5 . The method of  claim 1 , wherein the data imported is in d×f format. 
     
     
         6 . The method of  claim 1 , wherein the at least one subset is created where a surface of the three-dimensional image is to be created. 
     
     
         7 . The method of  claim 1 , further comprising creating curve offsets on at least one subset of loops. 
     
     
         8 . The method of  claim 7 , wherein creating curve offsets is performed by inserting a fillet within the curve. 
     
     
         9 . The method of  claim 1 , wherein contouring the at least one subset of loops is done with dynamic modeling. 
     
     
         10 . The method of  claim 9 , wherein the dynamic modeling involves creating the contour area from a shape. 
     
     
         11 . The method of  claim 10 , wherein the shape is a sphere, cylinder, ellipsoid, cone or plane. 
     
     
         12 . The method of  claim 10 , further comprising changing parameters of the shape. 
     
     
         13 . The method of  claim 12 , further comprising generating a wireframe over the image to show changes in the parameters. 
     
     
         14 . The method of  claim 1 , further comprising adding text to the image. 
     
     
         15 . The method of  claim 1 , further comprising triangulating the contoured area. 
     
     
         16 . The method of  claim 15 , wherein triangulating the contoured area comprises selecting curves from the contoured area, offsetting the curves by a uniform distance and creating triangles between the offsets. 
     
     
         17 . The method of  claim 16 , wherein projecting the geometries comprises projecting the vertices of the triangulated contoured area. 
     
     
         18 . The method of  claim 16 , wherein smoothing the image comprises selecting a centroid of each triangle, choosing a vertex and averaging centers of the triangles containing the vertex. 
     
     
         19 . The method of  claim 1 , wherein the geometries of the contoured area are projected onto a surface representing a shank of a ring. 
     
     
         20 . The method of claim I, further comprising generating a tool path.
