Business Needs: For a Finnish client, using Three.JS (also SVG, WebGL and Canvas/ HTML5/CSS are applied) to visualize of many drills underground. Within the project, we develop a whole management system with module to show the border of the hole and how were drills worked. Also, we are able to re-form the surface of the hole before and after drills work. The module can provide various user-friendly functions to interact with the 3D models. User can zoom in/out, pan, rotate, select/pick… in models.
