Abstract
ABSTRACT Field geological practice is not only an important part of teaching. However, how to vividly explain the geological practice in the field and intuitively show the geographical environment and its evolution is a difficult problem for geological educators. In this study, we use Pingtan Island as a research case. Based on HTML 5 and open-source framework Three.js of network graphics library WebGL, 3D interactions were embedded in the website. Besides, POI was built through Java, and annotation and image information were marked so as to realise data uploading, navigation, and 3D simulation platform functions. The research is to form a theoretical and practical teaching system.
