Constitute The Study Of The Composition Rules Of The System, Based On The Folk Art Of The Digital Image Plane

This paper describes the theoretical research and software development about the application of the Computer Aided Folk Art Plan Design. According to mathematics and computing technology, the thesis has been explained to the artistic creation of computer-basic principle and technological tactics of the Art Plan Composition that have been researched and developed in detail.Theory that this research used is the subdivision of Geometry figure. According to this theory, two-dimension picture is abstracted into a series of two-dimension regular geometry space: rectangle, isosceles triangle, isosceles and ladder-shaped etc. That is to say, the perceptual question of art are turned into the rational mathematic models for the computer programming. About the material of designing, the author presents the concept of "original graphic". The elements of geometry these have been drew on the plan, such as line, freedom curve, circle, round ring, rectangle etc. have been divided and used to divide the plan into some small parts according to the certain rule. Then, the selected picture are drew in the defined area quickly. In this way, the works are produced.Content of the research subject include the Art plane compositions theory, the compositions rules and constructing the mathematics model of the rules. In the research of plane art composition, the author focuses on "original graphics + composition rule". The emphasis is composition rules-looking for their characteristic, and setting up corresponding mathematics model and designing algorithm. By summing up the principles and methods of two-dimension art composition, the author builds five creation mode: line composition rule, freedom curve composition rule, rectangle composition rule, circle composition rule, round ring composition rule,. As to freedom curve, the emphasis is its expression and production-theory, in order to meet the requirement for art design, the thesis adopt "the accumulate String long Parameter two times Curve Producing theory", and realize the algorithms of curves production and subdividing.Finally, the composition rules module is realized on the platform of Visual studio C++ 6.0, and passed the debug. Instances of the plan composition generated by this module can meet the requirement. Basically, it has achieved the purpose of art design.
