How can I simulate plaster, sandpaper and rasp in Meshlab or other 3d manipulation SW? My 3d-scanned models appear quite "dirty", but if I physically had them in my hands I could fix them in minutes with plaster and sandpaper!Flattening or smoothing a surface should be the most used functions in 3d modeling programs... but I can't find such features anywhere!
Where do I find this STL file?!?
