Abstract


The simulation of the movement of the tree is an important part of the natural landscape analog . It is a very complex task , particularly with regard to branches fracture simulation , it is one of the problems in the motion simulation of the tree . Accordingly, the branches breakage is a very valuable and meaningful . The visual simulation branches breakage . Tree branches break the basis of visual simulation model . Tree branches and leaves . In this paper, the existing modeling methods and tools for analysis and simulation platform for research , Creator establishment of branches and leaves model , integrated in Vega Prime will be the model of various branches and leaves model , the establishment of a pieces of the tree. Creator advantages addition to modeling toolbox , there can be programmed directly through the Open Flight API modeling for a limited time to build a large number of models , saving development time . Branches breaking sports model includes three important part of in the the branches swing model , the whereabouts of the model of the branches and twigs collision detection model . These sports model is based on aerodynamics and Newton 's second law of motion . In this paper, motion simulation method of the existing tree analysis , using Vega Prime mock objects drive technology branches breakage simulation . For the movement of the tree in Vega Prime Strategy class as a base class to create motion model derived class , movement control tree through the public interface functions compute ( ) . While taking advantage of the tree collision detection the Vega Prime collision detector . Vega Prime branches breakage visual simulation not only greatly shorten the development time and reduce the workload , but also has a realistic simulation results . The application of modeling tools Creator and Vega Prime simulation platform , not only greatly reduce the workload , and improves the tree motion simulation fidelity . Through simulation results show that the simulation of the effect of the authenticity and the efficiency of the method .
