I have a 3d building in shockwave;

I have one wall of the building that is not straight but curvy, a "serpentine wall";

I would like to establish hotspots on the wall such that when a user rolls over the hotspot area something will happen, eg the hotspot will light up or an onmouseover message will be generated;

the hotspots themselves are rectangular, though projected onto the serpentine wall;

I have been playing with modelsunderloc's #uvCoord, but frankly I can't seem to make sense of the values;

any thoughts?
