Write some Software

This is a coding project in C++ with OpenGL. Some background in OpenSceneGraph will be required. A basic understanding of the Qt GUI framework is helpful. I have an existing implementation of Screen Space Ambient Occlusion (SSAO) for OpenSceneGraph that I use in a Qt application. I need it to render properly in Qt's new QOpenGLWidget (which expects GL to render to a framebuffer object that Qt composits). The SSAO implementation renders properly in the legacy QOGLWidget. The existing SSAO implementation uses OSG PRE- and POST- render passes only to do the rendering work. The primary render pass produces an empty scene, which is likely why it doesn't work with QOpenGLWidget. The code to be improved is available on [login to view URL] at iraytrace/[login to view URL] The primary work should be accomplished in the SSAONode.h and [login to view URL] source code.
