Pattern Grading of Garment by means of Cumulative Matrix Transformation

Abstract

In the study mathematical expression is presented and the process of grading by means of cumulative matrix transformation carried out. The process of grading is based on the multiplication of the matrix with homogeneous coordinates of the segment with the matrix of cumulative transformation. This is the reason why grading can be carried out in only one intervention. The operating speed of this method is high due to the structure and properties of the basis dates used in the process of grading. The method makes sure the precisenes of grading, of the initial forms of the transformed segment of the contures of the parts of the cut and is independent on the direction of grading. The result obtained showed that the method has all those qualities that are necessary for pattern grading of garment by means of computers.
