The present contribution is aimed at numerical modeling and graphic post-processing of data obtained in simulation of three-dimensional hypersonic flow initiated by strong shock wave oncoming on molecular cloud and interaction detailing. Investigations and simulation of supernova explosions and wave processes extended outside by means of cosmic wind have important role in developing of ISM description methods. Numerical solution of task was performed on multicore computers. To increase the prediction quality about billion cell calculation grids were approved. The outlet dataflow after detailed simulation is very extensive. Information treatment for high gradient zones near shock envelopes demand from spectator facility to use the proper visualization tools, first of all an extensive volume or surface rendering, fast tracing of streamlines and surface paths. It is essential to understand the dynamic changeable structure and flow peculiarities to avoid any misunderstanding or artifacts of realignment in stream. Numerical experiments and post-processing were performed using in-house combined GPU and multicore parallelization codes.
