Abstract. This paper, based on the key-frame polygon sequence, proposes a method that makes use of dynamic correction to develop continuous animation. Firstly we use quadratic Bezier curve to interpolate the corresponding sides vector of polygon sequence consecutive frame and realize the continuity of animation sequences. And then, according to Bezier curve characteristic, we conduct dynamic regulation to interpolation parameters and implement the changing smoothness. Meanwhile, we take use of Lagrange Multiplier Method to correct the polygon and close it. Finally, we provide the concrete algorithm flow and present numerical experiment results. The experiment resultsshow that the algorithm acquires excellent effect.
By introducing some atmospheric models and selecting methods for minimum integration step size and optimum initial integration value, a program of real time and near real time landing point predicting together with weighted processing methods of many groups of landing point parameters were put forward. Engineering application showed: the above methods and program improved real time and near real time landing point predicting precision more greatly compared with previously used methods, which had proved their broad applicability.
This paper introduces the service-oriented architecture technology, and proposes the architecture model of Out-trajectory Data Processing in distributed environment. According to the demand and features of Ship-borne Out-trajectory Data Processing flow, it describes how to carry out cross-platform service integration by using the Service Bus Middleware, and provides a kind of typical distributed deployment strategy.
