Java3D实现散乱数据的三维重构

Three-dimension reconstruction of scattered data based on Java3D

针对煤场测得煤堆表面三维散乱数据的可视化研究,本研究提出了一种简单的得到三维散乱数据拓扑结构的方法,在此基础上进行了三次三角B-B曲面插值,及基于双B样条的曲面拟合,并用Java3D图形工具包实现了上述算法,得到的渲染效果比较接近实物,能够很好的表征原实物表面的各种特征,证明了该算法的有效性和可行性。

Based on the study of visualization about scattered data measured on the surface of coal area, a simple method of getting triangulation was presented, and a cubic triangular B- B surface in- terpolation was obtained on the basis of triangulation. Then, a surface fitting was accomplished on the basis of double B spline. The method was realized by Java3D, and the result was similar to the prototype. The validity and feasibility of this method were proved.
