| 摘 要： | 以钻孔资料为源数据,利用克里格为插值方法,生成了相关地层的规则网格数据,并基于IDL实现了地层三维的可视化,并运用了光度学、色度学的算法实现视觉效果,引入了消隐、光照模型、颜色模型等技术,增强了地层可视化的仿真效果。利用本系统,可实现实时放大、缩小、旋转、平移并对每一个地层表面调色等功能,使得难以观察的地层可以逼真的展现在人们面前,提高了人们对地层的认知能力。

| Abstract: | Taking borehole data as source data, we generated regular grid data of relevant strata using Kriging interpolation method in this paper. 3D visualization of specific strata is realized based on IDL. At the same time we also use algorithms of photometry and colorimetry to achieve visual effects. In order to enhance the photorealistic of strata visualization, some technologies were adopted such as blanking, illumination model, color model, etc.. The system functions include real-time zooming-in, zooming-out, rotating, panning and painting any surface of strata. The strata which are hard to observe directly in the past can be vividly displayed via this system, and the recognition ability of strata will be improved. |
