Hi Alberto, If I'm not mistaken, Android is a Linux ELF platform, so it would make sense to build up a cross-compiler from a vanilla GCC linux version instead than from cygwin's one, which builds Windows COFF binaries. Maybe they are just taking advantage of the environment (shell, unix tools,

Hi, the same way you created your quad you can create many quads ( have a look at osggeometry example ) or quad strip. Then run osgUtil::SmoothingVisitor on your Geode to get nice normals. It should be enough for what you want to do -Nick On Wed, Dec 8, 2010 at 4:35 AM, Alden Peterson
