GPS Skylink's products didn't exist. In fact the only thing that did were some scribbles on paper and some ideas in CEO Xulin Hu's head. Using that, I developed a loose 'prototype' using 3D Studio Max. Investors don't like scribbles, so we gave them these as the first draft.
This 3D model was a collaborative multi-step effort. I began building a simple model in SketchUp which then evolved into a more complex model. Still, SketchUp does not output polished 3D imagery. So I sent the SketchUp files and master plan to an artist in China who provided this rendering at a very, very low cost.
