This article in detail introduced the computer line segment cuts out the technology and the computer animation technology. The computer cuts out the technology is assigns the window to take the graph boundary, extracts the concrete information from a big picture which needs, demonstrates some partial picture or the view. The computer animation technology is the graph, the design and the picture or part of demonstrations on the screen, and the request which or prearranges according to the certain rule on the screen moves, the transformation, thus causes the computer to demonstrate the setting out condition change the graph. This article also elaborated the line segment to cut out the algorithm the basic principle and the use computer animation technology manufacture animation realization process. First, introduced the line segment cuts out the algorithm, cuts out the algorithm including three kinds: Cohen-Sutherland cuts out the algorithm, the center point division cuts out the algorithm, Liang Youdong -Barskey cuts out the algorithm. Next, introduced the computer animation technology manufacture animation realization process. Moreover, this article also in detail introduced in the introduction the computer animation concept as well as the computer animation in each domain application, lets the reader in reading this article time has an preliminary understanding to this new technology. Key word: Reduction, animation, algorithm
