The Security Icon Generation Based On 3D Graphics

The anti-counterfeiting technology research and application not only to maintain economic interests of producters, but also to protect the interests of consumers, while a blow to the lawless fakes.The holographic anti-counterfeiting technology in the trade mark anti-counterfeiting technology is the most widely used anti-counterfeiting, forgery produced using this method has a pictorial icon fine, three-dimensional characteristics of rich, but the technique is simple and easily master criminals, and anti-counterfeit labels have easily copied and re-use shortcomings. Code security technology, with the rapid development of science and technology in recent years, resulting a information anti-counterfeiting technology, but the anti-counterfeiting technology, a single security code patterns.Combining holographic anti-counterfeiting technology and the advantages, proposed a technology to generate security icon based on 3D graphics and digital printing.The technology will combine goods digital code to the 3D graphics, making the icon design looks more beautiful, more three-dimensional at the same time, This technical security capability, simple operation, high technology, commodity trade mark creation and printing to achieve simultaneously, to avoid be imitationed by icon inventory.Mapped digital coding to three-dimensional model of the local area, digitally encoding be as texture image, proposed a center-spread and center constraint with the local area texture mapping. In this method, the initial seed surface as the center spread with breadth-first search method to determine the mapping region,and center constraint method be used to calculate the texture coordinates to ensure that the texture image center correspond to the texture mapping area center, avoid the texture image center in the center of the mapping area offset problem, the mapping region are more rounded shape. It has also set the texture scale variables, to achieve the zoom effect on the texture. Bunny rabbits as a model for a variety of texture mapping experiments show that method is feasible.
