Visualization Research on Realistic Forest Scene

Abstract

The three-dimensional visualization of virtual forest scene is a key technology for forestry informationization. Due to the large amount of calculation of large-scale forest scene, most research methods or softwares tend to adopt simplified tree models, which make user‘s experience not friendly and sense of reality poor. In this paper, a hierarchical parameter modeling method under the restriction of biometric is preferred, which can guarantee both the authenticity of the data and the speed of modeling process. Model library based on a serial of tree models of different level of detail is established, which can provide convenience for rendering forest. With the support of powerful SpeedTree SDK, the speed and accuracy of rendering will get effectively balance.
