Hi Er, Firstly, I have to say that my English is poor(not a good student in university...now I regret very much)and I learn OSG and C++ for a short time, but I like them very much. Yesterday I used the osg-user for the first time, Mr Wang Rui told me that I can ask for some help here, so I am here now. :) The way it is, I modeled in SolidWorks and then I derived model as STL format(SolidWorks can only export STL and VRML, and I perfer to use STL, STL is more current). When I use OSG to show the model, I found that the model is very angular, every surface shines...This is not what I want, I hope it looks more smooth, so I use the SmoothVisitor, but the old smoothvisitor smooth too much ,the model looks a little terrible ,OSG v 2.9.10 have new function which can set the creaseAngle, Firstly some error happened, Wang Rui change some code to make sure the SmoothVisitor is compatible with BIND_PER_PRIMITIVE, but after this the model looks as same as before, I changed the STL model, the creaseAngle, they don't work. Then I read the source code...read and read...near a week...finaly I found that I can't understand how it works. Now I am helpless, How can I smooth the STL model?
