Research On Graphic Construction Method Based On Medial Axis Transformation

Graphic construction technology is an important graphic design method,which not only has important applications in computer-aided design and computer-aided engineering,but also plays an irreplaceable role in many other engineering fields.At present,the main graphics construction technologies such as solid composition and curved surface composition have various degrees of deficiencies in composition information recording,graphic integrity description and graphic reusability,etc.,these make research on efficient graphic construction technology becoming a hot research in a field of computer-aided design.Based on the above current situation,after analyzing the current research results in this field and on this basis,a graph construction method based on medial axis transformation is proposed to solve some of the problems in the current graph construction process.The graph construction method of the medial axis transformation proposed in this paper is based on the relevant theoretical knowledge of the medial axis and its owm strict mathematical definition.The topological data structure is used to save the medial axis segment and the corresponding feature parameter information,and the medial axis segment is extended.The medial axis mapping principle and the medial axis transformation method generate boundary data corresponding to the medial axis segment,and finally construct a graph.Use this method to construct graphics,retain the medial axis skeleton information and record the composition process information through the topological structure,use the medial axis segment control points to ensure the interactivity during the construction of the graph,construct the similar graph through the modification of the characteristic parameter values,based on the medial axis mapping The relationship and the medial axis transformation method are used to generate the boundary of the graphics,so that the relationship between the composition information record and the overall description of the graphics can be taken into account to a large extent,and the construction efficiency and reusability during the construction of the graphics are improved.This paper designs related experiments to provide the verification of the feasibility and effectiveness of the graphic construction method proposed in the article.In the experiment,the Visual Studio development environment is used to program the case program.The openGL technology and SolidWorks tools are used to render graphics.And the visual rendering result is finally achieved,and the expected goal of composition is finally reached.
