The following screen shot is taken from a simple 3d modeler I developed during my Fall 2000 semester. It was developed under IRIX using C++, Open GL, and GLUI. The program is  incomplete however, and development is on permanent hold. As of now, it exists as a stand-alone modeler, incapable of reading external file formats. The project was basically an experiment to learn Open GL and get familiar with the GLUI toolkit.
