Yes, I did an experiment with a uniform mesh about a month ago. It turned out to be a choice between awful detail level, miniscule view distance or unusably slow framerate, so I abandoned it after a day. But it was a useful experiment because it really made me understand my triangle budget.

I do have a large background in computer graphics. If I lost the knowledge and had to reconstruct it again, I would begin by writing simple demos in the lowest level environment I could find. Forget Papervision, try making a spinning textured cube by assigning colors to individual pixels using C code. This way you pick up the background awfully fast.
