     BACKGROUND OF INVENTION  
       [0002]     While working with fingernails and fingernail objects for several years, there was no easy way to automatically create a three-dimensional model of an artificial fingernail object. In fact, most software in the market allows a user to manually manipulate and create just about any three-dimensional object conceivable, but the process of doing this manually is very time consuming and allows for too much human error when creating artificial fingernails with a consistent and reliable appearance. Because of this the inventors set out to find a method to create artificial fingernail objects automatically and this invention was the result. Through careful analysis and study, the key reference points outlined in the Claims section show how to focus a computer software modeling program on a few critical points and then with the help of some supplied parameters relating to expected lengths, widths, heights and curves a desired artificial fingernail object will be automatically created. This new desired three-dimensional object has many applications, not the least of which is the ability to physically create the nail object for the individual and supply them with an artificial nail for use as a cosmetic or even prosthesis. The invention can now save time and virtually guarantee consistent looking fingernail objects, all accomplished with relative ease.  
       SUMMARY OF INVENTION  
       [0003]     The invention is a method, process and computer program to automatically create a customized three-dimensional artificial nail object based upon an actual/existing digitized nail surface. This particular invention generates the overall desired three-dimensional nail surface by using key reference points contained in the digitized nail surface to automatically create new three-dimensional data along supplied parameters. The application of the invention results in a wide scope of possible implementations including a use for creating artificial fingernails and artificial toenails.

     DETAILED DESCRIPTION  
       [0010]     By starting with an existing digitized three-dimensional surface point array of an actual fingernail or toenail, the invention permits the automatic creation of a new customized three-dimensional object that will fit over the actual fingernail or toenail. This is accomplished by evaluating key points of data contained in the digitized array and by correctly interpreting the reference points and combining with the supplied parameters a new three-dimensional object can be generated, which when combined with the existing digitized three-dimensional object, will create a desired artificial nail object.  
         [0011]     The key reference points may include all of the points of data contained in the digitized three-dimensional surface array. However, it is more likely that the following key reference points are used to create the top surface: periphery points, the points along the Y-Axis in the middle of the X-Axis, the points located along the X-axis measured at approximately ⅔rds the distance along the Y-axis from the cuticle end of the nail surface. These reference points are then combined with supplied parameters which may be either constants or changed at the time the desired nail object is generated. The supplied parameters include curves, length, widths and heights. The supplied parameters work with the key reference points to create an expected and desired new three-dimensional object that will fit over the actual fingernail or toenail.  
         [0012]     In  FIG. 1  the first step of the process is demonstrated, where a digitized nail surface  100  is shown and the orientation of the X, Y and Z Axis is established. Here the X-axis  110  is found along the width of the digitized nail surface  100 ; the Y-axis  120  is the length of the digitized nail surface  100  and can be determined initially by measuring from the cuticle to the tip of the digitized nail surface  100 ; and the Z-axis  130  represents the height or depth of the digitized nail surface  100 . Orienting the three-dimensional data is necessary in order to measure the digitized nail surface  100  and determine the key reference points which are used in conjunction with the supplied parameters to create new three-dimensional data representing the top surface of the final three-dimensional nail object.  
         [0013]     Measuring the digitized surface area includes creating a relationship of the X-axis  110 , Y-axis  120  and Z-axis  130  to millimeters or inches, further arcs and curves of the digitized nail surface  100  are determined by measuring and creating relationships between the three-dimensional points of data along the X-axis  110 , Y-axis  120  and Z-axis  130 . These curves and arcs are utilized and manipulated in creating the top surface and eventual desired three-dimensional artificial nail object.  
         [0014]      FIG. 2  demonstrates the determination of the points along the Y-Center line  200  by taking the sum of points along the greatest X-axis  110  and dividing that by 2 to end up with a midpoint within the X-axis  110 . This centerline reference is then utilized to find the center of the digitized nail surface  100  and all of the points along that axis in the Y plane are then utilized to help determine the arc, curve and position of the Generated Nail Surface  500 .  
         [0015]      FIG. 3  shows another key reference point being determined by taking ⅔rds of the distance of the greatest Y-axis  120  from tip to cuticle. Once that reference point is determined then all of the X-axis  110  points are utilized to help determine arc, curve and position of the Generated Nail Surface  500 . The intersection in this case between the X-axis  110  and Y-axis  120  represents the highest point of the Generated Nail Surface  500 , which will be no greater than 25 millimeters from the Digitized nail surface  100 .  
         [0016]     Once the reference points creating heights, lengths and arcs are determined, then  FIG. 3  shows the determination of the periphery points  400 . This step is vital to insure that the new Generated Nail Surface  500  will fit over the Digitized nail surface  100 . The periphery points  400  are combined with the supplied parameters to determine the top surface of the Generated Nail Object  600 .  
         [0017]     With all the key reference points in mind,  FIG. 5  shows the actual new Generated Nail Surface  500  which is a three-dimensional array of data created by the reference points in relationship and combination with supplied parameters indicating the overall desired nail object. The supplied parameters include the desired length, height and width preferences for the desired nail object. The Generated Nail Object  600  combines the top surface calculations with the digitized nail surface  100  to create one consistent and expected artificial nail object. The new nail object will be customized to each particular digitized nail surface  100  and will fit on top of the digitized nail surface  100 .  
         [0018]      FIG. 6  shows the Generated Nail Surface  500  combined with the Digitized Nail Surface  100  as one Generate Nail Object  600 , fitting over the top of the original Digitized Nail Surface  100 .  
         [0019]     By completing the steps above, virtually any software program or user would be capable of generating a desired and customized three-dimensional artificial nail object. The entire objective of the preferred embodiments of the invention has been to create a simplified method, process and computer program to automatically create a customized three-dimensional nail object. The application of this invention is extensive and plentiful, as with this invention it will become trivial to generate desired three-dimensional artificial nail objects by automation quickly and easily. Because of the advantages inherent in this invention it is anticipated that many variants of this invention are possible, which should be included within the preferred embodiments and descriptions of this invention.
