Abstract


Simulating sky-scene is indispensable for virtual reality and scene simulation. The sky background corporeality for users can greatly increase the visual enjoyment and immersed sense. Therefore, an Dynamic, integral the sky scene is to reflect the entire virtual 3d system must have realistic. But now main rendering ways of the sky model also only stay in loading static pictures texture stage, that limiting flexibility and realism of the sky scene generation. And at present the method of generating dynamic sky textures exist fatal defect that dynamic elements is not enough for the generating dynamic sky .so this paper analyses more perfect dynamic sky scene generation algorithms on the basis of the study of former presents .This paper based on astronomy, atmospheric physics and atmospheric optical basic knowledge as the foundation, adopt digital image processing technology, again complementary with a lot of physical pictures to analyzes a phase of each time period the sky scene dynamic generation algorithms.Main contents of this article are as follows:(1)Based on the scene of time axis, with the sky scene each generation elements attributes as research object, by various elements with the right for final target, formulate the whole dynamic sky scene generation the key ideas.(2)Using digital image processing techniques generated the sky scene component elements of digital image, generate results very good embodies the constituent elements established attributes.(3)Using digital image processing techniques reasonable combination of sky scene of the component elements formed the ultimate dynamic sky scene.
