Calculation of Foliage Mass and Foliage Area
Introduction In Finland, the forest canopies are the main source of the volatile organic compounds (VOC). These forests are representative of the boreal ones, and they cover about 80% of the total land area of the territory of Finland. The forests throughout the country are utilised commercially and managed regularly with the consequence that the natural tree species composition is much affecte...
متن کاملRadio Wave Propagation Through Foliage
Wireless technology continues to experience rapid growth and development. With the ever increasing demand for wireless services and applications, more advanced tools are necessary to ensure the performance of these wireless systems. One of the most important tools for system development and radio planning are the radio propagation channel models. These models allow system designers and radio pl...
متن کاملView-Dependent Hierarchical Foliage Simplification
High compression of plant geometry is an important aspect in fast realistic visualization of plants. Hierarchical structuring plant morphology is a key factor for real time plant rendering, especially when pedestrian views, including both close-ups and far views, are requested. We present here a new geometric simplification method, called Viewdependent Hierarchical Foliage Simplification (VHFS)...
متن کاملMultiresolution foliage for forest rendering
Plants are important objects in virtual environments. High complexity of shape structure is found in plant communities. Level of detail (LOD) of plant geometric models becomes important for interactive forest rendering. We emphasize three major problems in current research: the time consumption in LOD model construction and extraction, the balance between visual effect and data compression, and...
متن کاملGeometric Simplification of Foliage
One of the most important challenges in real-time rendering of outdoor scenes is the representation of vegetation. This is due to the vast amount of polygons that are used to model vegetable species. The present automatic simplification algorithms produce acceptable results in the trunks and the branches, but not in the foliage of a tree. After simplification with the existing methods, the tree...
