Great! It seems that you are going to re-implement a nice texture merger. A very up to date description of our internal tool have been recently published on Computer & Graphics Masked photo blending: Mapping dense photographic data set on high-resolution sampled 3D models http://dx.doi.org/10.1016/j.cag.2008.05.004 it is based on the idea of using various blending channels (one is similar to your normal wrt camera) and you can find a copy of that paper at http://vcg.isti.cnr.it/~cignoni/CG_textailor_final.pdf a question Have you looked at the code in the filter sampling plugin? there is an example for generating all the texels of a given texture parametrization that, if i have well understood your pipeline, should fit well to your needs and should avoid the need of a quadtree (and you know that i definitely like to reduce the code around...) cheers p.
