Research on virtual growth measurement of Sabina vulgaris

In past work, a dynamic model of S. vulgaris shrubs was discussed based on improved dual-scale automaton model with the data from experiments. The dynamic model described the clonal growth of S. vulgaris more accurately in natural environment, and the model has been visualized by using C++ Builder. The effect of 3D drawing and rendering showed the similarity of virtual model and true plant more effectively. But the measure of virtual growth state hasn´t been solved in every growth cycle, for example, virtual growth height of S. vulgaris in each year can not be known. So the veracity of model can not be validated. It´s difficult to the further study. In this work, the centimeter units were used to modeling. The internode length, branching angle and curvature can be quantized in order to calculate plant height. The growth height of virtual plant can be measured by clicking relevant points on the screen. Comparing to actual S. vulgaris, the result indicates that the model can characterize the growth of S. vulgaris more truly. The visualization indicates that the model is highly consistent with the growth of true S. vulgaris.
