Abstract:

Trees are one of the most important natural features in the forest virtual scene rendering. The three-dimensional visualization model is proposed based on formal language of parametric and random L-system. According to the viewpoint in the spatial position, the model dynamically classifies stand levels of details which are described by various processing for rendering. By adjusting L-system iteration, models of hierarchical storage of tree, and bill-board approach, these levels of details are rendered separately. Experimental results show that this approach is an effective way to simulate forest virtual scene and it meets three-dimensional reality and real-time visualization requirements.

Key words: forest, L-system, three-dimensional visualization, LOD
