Abstract

Claims (48)

1. A computer implemented method of creating a triangulated surface for engraving an item, the method comprising:

selecting text or symbols;

spacing the text or symbols;

mapping the text or symbols between first and second curves;

identifying areas for clean up by estimating where sharp edges are likely to result and generating clean-up lines for the elimination of sharp edges and burrs, the clean-up lines defining trimmed surfaces;

generating triangulated surfaces from the mapped text or symbols and the trimmed surfaces; and

converting the triangulated surfaces into machine readable instructions for the generation of a tool path.

2. The method of claim 1 , wherein selecting text or symbols further comprises selecting at least one divider and wherein spacing the text further comprises placing the at least one divider and mapping the text or symbols comprises mapping the at least one divider.

3. The method of claim 1 , wherein spacing the text or symbols and placing is performed on the basis of the selected text or symbols.

4. The method of claim 1 , wherein the first curve has a shape different from the second curve.

5. The method of claim 1 , wherein the first and second curves form a bezel.

6. The method of claim 1 , wherein areas for clean up includes text with center islands and a lower rim.

7. The method of claim 6 , wherein generating clean-up lines includes generating clean-up lines for each character of the text.

8. A method for creating a triangulated surface convertible to a series a machine readable instructions, the method comprising:

defining a shape for placement of text and/or symbols;

defining the text and/or symbols for placement on the shape;

placing the text and/or symbols on the shape as a first set of triangulated surfaces;

identifying areas for clean up by estimating where sharp edges are likely to result and generating clean-up lines for the elimination of sharp edges and burrs the clean-up lines defining trimmed surfaces;

generating a second set of triangulated surfaces from the trimmed surfaces; and

converting the sets of triangulated surfaces to machine readable instructions for generation of a customized item.

9. The method of claim 8 , wherein the shape comprises an upper and lower closed curve.

10. The method of claim 9 , wherein placing the text and/or symbols comprises spacing the text and/or dividers within the upper and lower closed curves.

11. The method of claim 10 , wherein the placed text and/or symbols are mapped between the upper and lower close curves.

12. The method of claim 11 , wherein triangulated surfaces are generated from the mapped text and/or symbols.

13. The method of claim 8 , wherein the text comprises one or more lines of text.

14. The method of claim 8 , wherein the triangulated surfaces are converted to machine readable instructions for the generation of a tool path.

15. The method of claim 8 , wherein the triangulated surfaces are converted to machine readable instructions for the generation of a photorealistic image.

16. The method of claim 8 , wherein the triangulated surfaces are converted to machine readable instructions for the generation of a rapid prototyping model.

17. The method of claim 8 , wherein areas for clean up includes text with center islands and a lower rim.

18. The method of claim 17 , wherein generating clean-up lines includes generating clean-up lines for each character of the text.

19. A non-transitory computer-readable storage medium encoded with a computer program code for creating a triangulated surface convertible to a series a machine readable instructions, the program code causing a computer to execute a method comprising:

defining a shape for placement of text and/or symbols;

defining the text and/or symbols for placement on the shape;

placing the text and/or symbols on the shape as a first set of triangulated surfaces;

identifying areas for clean up by estimating where sharp edges are likely to result and generating clean-up lines for the elimination of sharp edges and buns, the clean-up lines defining trimmed surfaces;

generating a second set of triangulated surfaces from the trimmed surfaces; and

converting the sets of triangulated surfaces to machine readable instructions for generation of a desired output.

20. The computer-readable medium of claim 19 , wherein the triangulated surfaces are converted to machine readable instructions for the generation of a tool path.

21. The computer-readable medium of claim 19 , wherein areas for clean up includes text with center islands and a lower rim.

22. The computer-readable medium of claim 21 , wherein generating clean-up lines includes generating clean-up lines for each character of the text.

23. A computer system for creating triangulated surfaces for engraving an item, the system comprising:

a personalization client module comprising a processor configured to generate a tool path for a milling machine to create the item; and

a database having information relating to the geometry of the item including computer readable instructions executable by the personalization client, the instructions comprising the operations of:

defining a shape for placement of text;

defining the text for placement on the shape;

placing the text on the shape as triangulated surfaces, wherein placing the text is performed on the basis of the defined text;

mapping the text on the shape, wherein mapping includes determining maximum and minimum expansion factors for the text and mapping based on these expansion factors; and

converting the triangulated surfaces to machine readable instructions for generation of a customized item.
