Just a quick note that the gPoly development has been slow recently. About two weeks ago I worked a bit on the texture mapping on the polygons, but since then I have been kept busy with other things. Mainly work, but on the other hand I have also been working on the ModelConverterX tool to improve the COLLADA conversion so that SketchUp can be used as a modelling tool. At the moment that has a slightly higher priority, but after that I will return to the gPoly development again.
