ABSTRACT:
A method and apparatus for flattening a three-dimensional surface into a two-dimensional pattern piece extracts a three-dimensional mesh from the surface to define surface elements and maps these elements in groups to a flat plane where they are reassembled. The position of data points in the flat plane are recursively adjusted in order to cancel error and to provide an optimum solution. Tools are provided to the user to determine the correctness of the flattening process and to insert darts into, and make other modifications to, the resulting flat pattern in order to further optimize the result.
