Realistic image synthesis of flying scenes of spacecraft

Photo-realistic image synthesis of dynamic flying scene of spacecraft and outer space scene is really a new challenging task for the researchers of computer graphics. In this paper a new method to realistically render the flying scenes of spacecraft is proposed. In the new method, based on Hipparcos Catalogue in Astronomy, authors first construct and render the dynamic scene of outer space sky with stars accurately at different viewpoints and at different time by adapting the accelerated rendering techniques such as image based modeling and rendering, level of details. According to the principle of astrophysics, the flying track of the spacecraft is determined. The flying scene of spacecraft with outer space background is thus generated. Then, based on the principle of quantity optics and radiance of plasma, authors model the reentry process of the spacecraft and determine the reentry trace, the colors and shapes of the turbulent trail and wake flow of the spacecraft. Finally, realistic images of the spacecraft with fantastic wake shape and color during its reentry through the atmosphere at different phases are drawn.
