Modeling 3D Tree Based on Growth
Hong Liu · Jisuanji fangzhen · 2006
The basic goal of 3D modeling is to generate virtual object of third dimension which can compare beauty with real one through acceptable complexity of algorithm. Static approaches of modeling 3D tree generally utilize fractal features and stochastic features of tree. We propose a dynamic method based on tree’s growth. Tree’s growing process is affected by inner gene and outer circumstance. So it can be generated tree model by dynamic controlling the growth of tree. The notion of force has been introduced in the dynamic modeling system to control the process of tree growth. There are two kinds of force, called inner force and outer force, which simulate life-force and environmental factors respectively. Combined with fractal mechanism, the system can generate various ordinary state trees. Another virtue of the dynamic system is that it can expediently control the outcome. By adjusting arguments of force, the results can be smoothly changed and deliberately controlled.
