Clothes surface simulation by constructive geometry methods with application graphical keys of proportionality

Creation of software for the automated model building surface wear as the frame (of two mutually orthogonal lines belonging to the surface) is the subject of consideration in this work. Modern methods of obtaining initial data for the design of light industry and, in particular, clothes allow you to use not only the numerical values of dimensional attributes, but some form of curves on the surface of the human body. So the challenge presented by the transition curve to the surface of the future product, or building surface known curves belonging to the desired surface, while maintaining some smoothness of the surface. To achieve the objective formulated such problems have been solved. The analysis graphic-plastic and surf-graphical keys proportionality building surface in terms of the existence of solution of the problem submitted to the original data. The necessary and sufficient conditions for the existence of surfaces that can be constructed using graphic-plastic and surf-graphical keys proportionality have been formulated. The software construction of the frame surface with graphic-plastic key proportionality has been developed. The software construction of the frame surface using surf-graphical key of proportionality has been developed. Means for input source and output boundary curves constructed frame on the monitor screen and on solid carrier of information. Using developed methods allows to reach high level of correspondence ednd results to teste of customer
