Real-Time Cloud Modeling and Rendering Approach Based on L- system for Flight Simulation

Modeling method to render cloud on the simulation is divided into two schemes, static and dynamic, depending on the accessibility of the cloud. Two schemes show the complete dissimilar properties in the aspects of realism and real-time processing. Thus, in this paper, we propose a new scheme that merges two modeling methods of the cloud for flight simulation by using the L-system. Since the proposed scheme considers both realism and rendering speed, it is possible to be implemented the formation and growth of the cloud in real-time manner. Finally, the proposed method is evaluated by the experimental results of real implementation in the flight simulation software based on OpenSceneGraph(OSG).
