Abstract

For the rapid visualization of large-scale forest scene, this paper proposes a real-time recombination method of complex 3D tree model information. This method adopts visual attention model and the visual characteristic of tree structures, then uses geometry-based and image-based methods to simplify tree models and construct a hybrid representation model for the 3D tree models based on the visual perception. It reflects the visual perception features of 3D tree models that can embody topological semantics in dynamic simulation. Finally, the method in this paper is applied to the simplification of several tree models, and compared with some existing tree model simplification methods. The experimental results show that this method can not only preserve better visual perception of 3D tree models, but also effectively decrease the geometric data of the forest scene, and improve the rendering efficiency and real-time walkthrough speed of forest scene.
