Computer Two-dimensional Animation Distortion Engineering Research

The computer animation is the product which the computer graphics and art unify, is continual has the third dimension picture with the computer production. The two-dimensional polygon gradation is in computer animation basic strokes, is refers to from the polygon to the goal polygon visual transition. The two-dimensional physique changes gradually the research contains two questions: Apex correspondence question and apex interpolation way question. This article in analyzes and in the quite existing two-dimensional polygon gradation algorithm foundation, proposed based on the visual plane physique's gradation method, and has based on this given a two-dimensional animation distortion method, may realize contains the multi-regions the physique distortion.The author to proposed in the present paper based on the visual characteristic's plane physique gradation a new method, establishes between two plane physique characteristic point the correspondence. planar image blending,visual feature,region matching,interpolation,animation.The method extracts feature points from source and target shapes,A new similarity metric between two feature points is defined using the rectallgular region centralized on them and distance between feature points.The optimal correspondence is found by dynamic programming technique.The two-dimensional animation distortion method is the physique which is composed of many enclosed areas carries on the distortion. This method mainly includes four parts: The region segmentation module, this module expresses the user input's contour line moves the territory role decomposition; The region match module, this module decomposes the outset frame and the termination frame and corresponds; Corresponds the region interpolation module, in this module uses based on the visual characteristic plane physique changes gradually the method interpolation production every time for the region middle gradation region; Region adjustment and combination module, module final middle frame output.The massive emergence's independent animation work favors from the connotation to the form the individual element display, regarding the animation language's exploration the impetus function. Computer animation art and the animation language unify, is not only advantageous to the outstanding computer animation work creation, will speed up our country computer animation industry the benign development. The Flash animation in platform and so on Internet, movie, television, handset dissemination has a greater economic value. And becomes our country animation industry newly to create income the spot, seizes the market share for the domestically produced original animation, to seek the recent development to provide a turning point.In short, in computer technology become more and more widely used today, computer animation is walking into the millions. Research on computer-based 2D animation, both for now and the future of animation design direction has real meaning.At last summarize the work I do and give some advices about the next research.
