Timothy R Littlefield - Web page: https://patentgrep.com/patent/US8787657B2 ## CPC - G06T 17/10: Constructive solid geometry [CSG] using solid primitives, e.g. cylinders, cubes - G06T 19/00: Manipulating three-dimensional [3D] models or images for computer graphics - G06T 2210/41: Medical - G06T: IMAGE DATA PROCESSING OR GENERATION, IN GENERAL ## Abstract Apparatus for processing a digital mesh representing a three-dimensional subject automatically filters out portions of a predetermined color to simplify further processing. ## Claims ### Claim 1 A method, comprising: providing a first data file representative of the shape of a three-dimensional subject; providing a second data file comprising a three-dimensional digital photographic data file representative of said subject and corresponding to said first data file, said subject comprising a first portion having a predetermined color; and utilizing said second data file to identify a corresponding first portion of said first data file corresponding to said portion having said predetermined color; providing said first data file with data representative of a plurality of polygons arranged into a mesh representative of said subject; and utilizing a color selective algorithm to selectively identify a first color portion of said second data file corresponding to said predetermined color. ### Claim 2 (depends on 1) A method in accordance with claim 1, comprising: separating said first data file first portion from said first data file to produce a modified first data file. ### Claim 3 (depends on 1) A method in accordance with claim 1, comprising: processing said first data file without utilizing said first data file first portion to produce a modified first data file. ### Claim 4 (depends on 1) A method in accordance with claim 1, comprising: capturing first data for said first data file and said second data file for said second data file substantially simultaneously. ### Claim 5 (depends on 1) A method in accordance with claim 1, comprising: identifying data in said first data file representative of ones of said polygons corresponding to said first color portion of said second data file; processing said data representative of said ones of said polygons corresponding to said predetermined color in a first manner; and processing said data representative of said ones of said polygons not corresponding to said predetermined color criteria in a second manner different from said first manner. ### Claim 6 (depends on 1) A method in accordance with claim 1, comprising: modifying said first data file to eliminate data representative of said ones of said polygons corresponding to said first color portion. ### Claim 7 Apparatus, comprising: a first data file representative of the shape of a three-dimensional subject; a second data file comprising a three-dimensional digital photographic data file representative of said subject and corresponding to said first data file, said subject comprising a first portion having a predetermined color; and a processor operable to utilize said second data file to identify a corresponding first portion of said first data file corresponding to said portion having said predetermined color; said first data file comprises first data representative of a plurality of polygons arranged into a mesh representative of said subject; and a color selective algorithm executed by said processor to selectively identify a first color portion of said second data file corresponding to said predetermined color. ### Claim 8 (depends on 7) Apparatus in accordance with claim 7, comprising: said processor is operable to separate said first data file first portion from said first data file. ### Claim 9 (depends on 7) Apparatus in accordance with claim 7, comprising: said processor is operable to process said first data file excluding said first data file first portion. ### Claim 10 (depends on 7) Apparatus in accordance with claim 7, comprising: capture apparatus to capture first data for said first data file and second data for said second data file substantially simultaneously. ### Claim 11 (depends on 7) Apparatus in accordance with claim 7, comprising: said processor is operable to identify data in said first data file representative of ones of said polygons corresponding to said first color portion of said second data file; said processor processes said data representative of said ones of said polygons corresponding to said predetermined color in a first manner; and said processor processes said data representative of said ones of said polygons not corresponding to said predetermined color criteria in a second manner different from said first manner. ### Claim 12 (depends on 7) Apparatus in accordance with claim 7, comprising: said processor modifies said first data file to eliminate data representative of said ones of said polygons corresponding to said first color portion. ### Claim 13 A method comprising: providing a data file representative of a three-dimensional subject, said subject comprising portions having a predetermined color; said data file comprising a plurality of polygons arranged into a mesh representative of said subject; processing said data file with a color selective algorithm; utilizing said color selective algorithm to selectively identify ones of said polygons meeting predetermined color criteria; processing all of said polygons meeting said predetermined color criteria in a first manner; and processing all of said polygons not meeting said predetermined color criteria in a second manner different from said first manner. ### Claim 14 (depends on 13) A method in accordance with claim 13, comprising: providing a modified data file comprising all of said polygons meeting said predetermined color criteria. ### Claim 15 (depends on 13) A method in accordance with claim 13, comprising: providing a modified data file comprising all of said polygons not having a preselected predetermined color.
