【摘要】 根据空间科学研究对交互性和Web化的发展需求,将Java 3D应用于该领域。深入剖析了Java 3D的主要几何类和实现细节;改进并实现了一种矩形网格等值线生成算法,解决了二义性和等值点在网格顶点的问题;介绍了一种生成规则网格的简单算法,并选用合适的Java 3D类加以实现;介绍了一种数值———颜色映射算法,并将空间环境数据映射为RGB颜色信息。综合运用这些算法,对地球空间环境中若干物理要素模型进行了二维和三维可视化。可视化结果与国内外空间环境模型研究成果基本一致,说明上述算法正确,有较高的参考价值。更多还原

【Abstract】 According to space science research’s development and requirement on interaction and Web,this paper applied Java 3D to this field.It dived into several common Java 3D geometry classes and details.It improved and implemented one rectangular net isoline tracing algorithm,solved the ambiguity problem and the case when isoline points appeared at grid vertexes.It introduced one simple method to generate regular net and implemented it with proper Java 3D class.It introduced one algorithm to map numeric value to color and mapped space environment data into RGB information.It also visualized some geospace environment physical elements models both in two-dimension and three-dimension based on these algorithms.Results are in line with those research achievements both at home and abroad.This verifies these algorithms’ correctness and high refe-rence value.更多还原
