Runge Kutta integration of basic idea is by repeatedly positioning and velocity interpolation restrain the error and improve the accuracy, is commonly used to project the single step but without losing accuracy algorithm. Among them, four order Runge Kuta performance is the best. The based on CUDA platform of fourth order Runge Kutta integration is realized. With the GPU powerful parallel computing ability, improve integral calculation speed, makes use of the fourth-order Runge Kutta integration calculation generated streamline visualization to achieve real-time requirements.
