Once we inspect the scene graph, we'll see that it contains quite a bit of redundant state. | Once we inspect the scene graph, we'll see that it contains quite a bit of redundant state. | ||
However, this is where osg::Optimizer can shine, by optimizing our scene graph to get rid of redundant state sets and flatten the scene graph. | However, this is where osg::Optimizer[http://trac.openscenegraph.org/projects/osg//wiki/Support/UserGuides/OptimizerOptions] can shine, by optimizing our scene graph to get rid of redundant state sets and flatten the scene graph. | ||

Next, we're going to explore dumping complex scene graphs to disk, i.e. those created by Canvas MFDs like the [[NavDisplay]] - so that we can check what the scene graph looks like after optimizing/simplifying it using osg::Simplifier and osg::Optimizer respectively, while also investigating which additional OSG properties may be helpful to expose for the optimizer/simplifier to provide satisfying results. | Next, we're going to explore dumping complex scene graphs to disk, i.e. those created by Canvas MFDs like the [[NavDisplay]] - so that we can check what the scene graph looks like after optimizing/simplifying it using osg::Simplifier and osg::Optimizer respectively, while also investigating which additional OSG properties may be helpful to expose for the optimizer/simplifier to provide satisfying results. | ||

Once a complex Canvas texture (MFD) has been set up, the following patch can be used for invoking osgUtil::Optimizer() to finalize and optimize the scene graph: | |||
