Realistic 3D-modeling of forest growth with natural effect

Abstract

At present laser scanning integrated with traditional air photography is a priority tendency for forest assessment and monitoring. This direction of research is based on modern technique of digital photogrammetry and geographic information systems (GIS), also on digital multidimensional signals processing. Terrain 3D-modelng with mapped growth is one of the main tasks during initial stage of virtual forest assessment. Proposed method permits to use LIDAR and air photography data for modeling terrain and rendering fractal texture of growth. Also our approach includes imitation of natural effects such as fog, rain, snow blanket and etc. © Springer-Verlag Berlin Heidelberg 2010.
