3D visualization of point clouds using HTML5 and WebGL

14206

The wide application of the 3D laser scanner leads to an urgent demand in visualization of point clouds which，however，is only limited to desktop-based solutions for years．As an emergent online 3D Engine，Web GL makes several web renderers become available． Addressed the current issues of online point cloud visualization，this paper proposed a method of web-based point cloud visualization without plug-in．The method combines ASP. NET and Web GL，by using the spatial database PostgreSQL to store data of different formats，and HTML5 to implement the user interface．A visualization system for 3D point clouds is developed by JavaScript with the web interactions．Finally，the method is applied to the real cases．Results of experiments prove that the method is very useful which avoids the shortcoming of current solutions for point clouds online．
