A binocular vision system for generating flames using particle volume rendering

Abstract

In the field of CG, billboards have been used to represent visual effects such as flames, smoke, and clouds. There are many known systems with such functionalities. However, since billboard representations do not depict the interior of objects, contradiction in appearance may occur depending on the location of the viewpoint. In addition, because of no accurate 3D depth information, the visual context may collapse when rendering with other objects. Furthermore, in a binocular virtual reality system, identical rendering results are generated for the left and right eyes, so that the closer the distance to the viewpoint is, the more three-dimensional cues get lost. In this research, we propose a system which can represent flames with minimal loss of stereoscopic effects from any viewpoint, and does not cause inconsistency in the binocular vision environment while providing an interface with common look and feel.
