Abstract

The invention relates to a method and a system for dynamic virtual simulation of a plant. The method comprises the following steps of according to a topology structure of the plant, establishing a mass spring model of the plant, and determining the number and quality of masses; according to the movement capturing feature point of the plant, capturing the movement of the plant within the continuous movement capturing time sequence, and recording the captured movement data frame; analyzing the movement data frame, obtaining the parameters of the mass spring model, and performing dynamic virtual simulation of the plant. The method has the advantages that by establishing a quantitative relationship between physical model parameters and real physical movement of the plant, the reasonableness and accuracy of the physical model parameters are effectively guaranteed, and the effect of virtual simulation of the plant is improved.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a plant dynamic virtual simulation method and system. Background technique [0002] Plant virtual modeling and simulation is an important and difficult problem in the fields of botany, agronomy and computer application research, especially the dynamic modeling and simulation of high-precision and high-realistic plants is more complicated. Plants continue to deepen in typical applications such as scientific research, virtual display, game entertainment, and horticultural landscape design. Traditional plant virtual modeling and simulation methods cannot meet the requirements of plant dynamic virtual simulation in various fields. Three-dimensional dynamic simulation and animation of plant objects Synthesis has developed into a hot topic. Proposing an accurate and efficient plant dynamic simulation method, establishing a high-precision and high-realistic plant dynamic vi...
