Andor talked about Arius3D. Arius3D is a type of 3D object scanner and is based on 17 years of research by the National Research Council Institute for Information Technology.Then he talked about PointStream 3D ImagePlayer for Windows. The problem with this is that it works with the Active X Plug-in and only works with Windows and draws 3D point clouds in IE. It requires installation and requires permissions. He told that why he used points and what a point cloud is. He later talked about polygons and then the difference between polygons and point clouds. The most interesting part was when Andor talked about the solution to the problem he mentioned above. He talked about XB(Cross Browser) PointStream which is an open source technology. It emulates Aruis3D's PointStream and streams data using JavaScript and streams and draws point clouds using HTML5. Thus Andor is working on the open source cross browser PointStrean using WebGL which is a subset of OpenGL. It gives direct access to the graphics card and is supported by all major browsers. Atlast, Andor showed a few demos of how this works and we can see a 3D image with PointStream on certain images using 3D glasses.
