Abstract


Of Red Fuji apple trees as the research object , by extraction of the morphological structure of varieties , with the help of computer-aided design thinking , the geometric model of the apple tree aboveground organs and organ growth deformation method , and Markov and implicit semi- Markov random process to describe the apple tree branching processes ; eventually the organic integration of the technical , visual simulation framework for the formation of the formation process of the morphology of apple trees , apple tree growth under natural conditions of virtual . The main work and results of this paper are as follows : 1 apple tree organs three-dimensional modeling : the characteristics of apple twigs round table to build three-dimensional model of the bending effect of branches and random bending parameters ; modeling of leaves and flowers cross quadrilateral and transparent textures ; using Bezier curves to create three-dimensional model of the apple fruit , the model has a less controllable parameters , the parameters of clear physical meaning and applicability . Apple tree growth simulation : Markov and semi-Markov implicit description apple tree branches branching mode , the mathematical model with accurate, objective , universal characteristics of strong , flexible to be extended to other fruit trees the branching structure of the tree species , varieties analog . Leaf Texture templates to achieve the blade dynamic growth effect , the way to achieve real-time processing requirements , can effectively generate the leaves of all ages with a realistic effect ; using linear interpolation method to simulate the growth process of apple flowers and fruits . Visual analog apple tree dynamic growth simulation system development : Combining these methods , visual simulation system developed apple tree growth in Visual C platform OpenGL graphics engine , and use of the system to achieve the natural growth of the apple tree .
