Design and Implementation of Individual Tree Growth Visualization System of Cunninghamia lanceolata

Along with the development of computer techniques,the application of computer in three-dimensional visualization simulation of plant growth process has been paid more and more attention. Taking Cunninghamia lanceolata as an example, the morphological parameters from the perspective of the visual simulation were designed and the trees’ morphological characteristics were analyzed based on the survey data.Combined with IFS(Iterated Function System) under the control of the growth curve,by using Object-oriented design methods, and according to API and model rendering technology provided by DIRECTX9.0,a three-dimensional visualization system on the growth and development of C.lanceolata individual tree were developed on the.NET and DIRECTX9.0 platforms,which realized the static and dynamic three-dimensional visualization simulation.
