Wind Rendering in 3D Modeling Landscape Scenes

The modeling of 3D landscape scenes includes two main issues: the creation of landscape scene and the natural effects rendering. A hybrid approach based on laser data scanning and templates of L-systems was developed to design trees and brush of various types and sizes. The space colonization algorithm was applied to make the tree models realistic and compact described and stored. Wind rendering is a necessary procedure, without which any modeling scene looks non-realistic. Three algorithms for wind rendering under changeable parameters were proposed. They have a minimal computational cost and simulate weak wind, mid-force wind, and storm wind. The approach based on mega-texture visualization was used to make a 3D landscape scene with wind effects a real-time application. The user can tune the various trees and wind parameters and manipulate a modeling scene by using the software tool "REWELS" designed in the development environment RAD Studio 2010.
