Starting point of this first version is this very simple algorithm: http://mikepan.homeip.net/ssaowcn
once this will perfectly work, then we can implementing a more complex one. there are many diferent papers describing how we can implementing high quality SSAO /adrian 2008/12/18 Raymond de Vries <ree...@xs4all.nl> > Hi Adrian, > > This looks very nice!
