Hello to everyone, I posted this in another section, but pheraphs it wasn't the right place. I would like to study the displacement mapping technique which uses dilation and erosion maps (http://www.cg.informatik.uni-siegen.de/data/Publications/2005/kolb05efficientskip.pdf): well, I don't find a program which creates dilation and erosion maps. Where can I find it? Any other suggestions are well-appreciated. Bye nicola
