Hi Sebastian, Just a heads up for changes I've just checked in relating to DisplacementMapping, I have moved the osgTerrain::GeometryPool pointer from osgTerrain::DisplacementMappingTechnique to osgTerrain::Terrain. I have made this change so that it's easier to local and manage the GeometryPool.
I am planning to tweak the way that the osg::Program is assigned to the StateSet's, instead of having them distributed across on each tile I'll place the osg::Program in a StateSet assigned to the Terrain. I haven't worked out the actual method for this yet but should wrap this up today. My idea is that only the change bits of state will be assigned to the tile related StateSet, the shared state will remain at the root of the terrain which of course is the Terrain node itself. I'll update this thread once I've done this. Robert.
