摘要
ＳＬＧＲＡＰＨ是一个应用于地质背景下的三维数据可视化系统．文中探讨了系统设计中采用的将面向问题域思想与面向对象技术合为一体的方法，使系统具有很强的动态可扩充性和较高的代码复用率．ＳＬＧＲＡＰＨ充分考虑了地层与断层的空间连续性，从立体角度建立完整的断层模型，并结合空间单元分割技术和区域编码法，较精确地实现了离散数据场的空间估计，较好地解决了断层问题．文中还提出了浮动水平线消隐算法和光线追踪真实感绘制算法的改进方法．
SLGRAPH, a 3D data visualization system on geological application is introduced in the paper. Its design technology incorporates both ideas of object orientation and problem orientation, which gives the system a higher dynamic extensibility and reusability of codes. SLGRAPH has well considered the dimensional continuity of stratum and fault, modeling them in views of 3D. Supported by the technology of dividing spatial cells and encoding by their regions, it figures the discrete 3D data field quite accurately and solves the problem of fault. Then, improvement of the algorithm of removing hidden lines by floating horizontal line and rendering by ray trace are presented.
