| 摘 要： | 随着科技的飞速发展,地质大数据正在呈爆炸式增长,地质大数据可视化与交互方法成为研究的新方向。如何通过可视化方法将巨大的、复杂的、潜逻辑的地质数据展现与交互是需要进一步探索的。本文提出基于VR技术的多尺度地质数据3D沉浸式可视化与交互方法,该方法既符合计算思维又符合地质专业理论。首先,从理论上提出多尺度地质数据可视化理论模型;其次,基于VR技术实现多尺度、多分辨率地质数据的可视化;最后,构建了3D沉浸式虚拟现实平台,采用实际数据验证方法的有效性。该方法适用于地质数据的可视化与交互,为科学的定量评价、分析和教学提供新思路,是未来的必然发展趋势。

| Abstract: | Rapid technology development leads to new direction of mineralogy exploration and teaching involving visualization and interaction of geological big data. Further exploration is needed on how to visualize and interact with the voluminous and complex geological big data which have no apparent logical structures. We have studied the 3D immersive visualization and interaction method for multi-scale geological data based on virtual reality (VR) and recognize the method is consistent with computational thinking and geological theory. In this paper, we first propose a theoretic framework for the multi-scale geological data visualization method. Next, we apply this method to visualize the multi-scale/multi-resolution geological data based on VR technology. Finally, we construct the 3D immersive VR platform and validate the method using actual data. We present here a new approach in visualization and interaction of geological data, as well as in scientific quantitative evaluation, analysis and teaching, illustrating an inevitable future development trend. |
