EMBOSS SHEET OF WOODY TEXTURE, CONSTRUCTION MATERIAL USING THE SAME, AND METHOD AND APPARATUS FOR FORMING EMBOSS SHEET OF WOODY TEXTURE

摘要

PROBLEM TO BE SOLVED: To express glossy patterns closer to a face of natural wood. ;SOLUTION: A vector field in a three-dimensional fiber direction indicating an orientation of fibers of natural wood is defined. The vector field is cut along a cut face J. A fiber submerge angle formed by a fiber direction vector F and the cut face J is defined for each point P on the cut face J (S10). Based on a transformation formula of the angle and an angle , the angle is transformed to the angle , and a direction vector V having the angle to a reference line R and included in the cut face J is generated for each point P (S20). A two-dimensional vector field is defined on the cut face J. Many shading lines M extending along the direction vector V are formed on the cut face J (S30). A pattern of the shading lines is formed to be projected and recessed on a transparent emboss sheet E (S40). The emboss sheet E is layered on a print sheet having a wooden pattern printed, whereby glossy patterns are expressed by streaks of the lines.;COPYRIGHT: (C)1998,JPO
