Hi Sajjad, it seem that osgPPU don't find osg library. You have to define the OSG_DIR environment variable on the OSG directory path and be sure this directory have a "lib" directory with osg libraries inside. You can also precise OSG libraries path directly in cmake. About osgstereomatch, I ca

Hi Robert, my application is in the context of technical research. So it is not just for creating a "good look". Imagine you need to calculate the flow of a filter textile. In this case you have to know exact thread geometries. My geometry has the following vectors: osg::ref_ptr osgVertices;
