lug-in working in the InSpeckEM software, lets you convert 3D models to point cloud.  After re-sampling the model texture, a diffuse error algorithm is used to create a black and white image.  A point cloud is generated using this B/W image.  Finally, the point cloud may be used to print any 3D models in a block of glass.
       roject done in April 2003.  The project was developed and compiled with Microsoft Visual Studio using the MFC library in C++ to build the User Interface.  The plug-in run under Windows 95-98, Windows NT-2000-XP and uses OpenGL to draw in 3D.
