5cd4faf05b From Jason Beverage, "I posted a question on osg users about resources not being properly released when using osgTerrain databases and multiple viewers are used a few weeks ago and I've found that at least part of the problem comes down to the fact that the nodes that are traversed by the GeometryTechnique are never actually added to the scene graph, and thus don't have releaseGLObjects called on them. I'm submitting a few changes that takes care of this by allowing the TerrainTechnique to provide a releaseGLObjects implementation. I've applied these changes in osgEarth and this example program no longer crashes on the second run, although I get corrupt geometry (see attached shot) which could be down to a driver issue. If I increment the context ID for the second viewer, I no longer get the corrupt geometry.
The attached changes are against OpenSceneGraph 2.8.2.

//Sample program.  Run against an osgEarth or VPB database based on osgTerrain.
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>

int main(int argc, char** argv)
{
   osg::ArgumentParser arguments(&argc,argv);

   osgViewer::Viewer* viewer = new osgViewer::Viewer();
   viewer->setUpViewInWindow(100,
100,500,500);
   osg::ref_ptr<osg::Node> loadedModel = osgDB::readNodeFiles(arguments);
   viewer->setSceneData( loadedModel.get() );
   viewer->run();
   delete viewer;

   viewer = new osgViewer::Viewer();
   viewer->setUpViewInWindow(100,100,500,500);
   loadedModel = osgDB::readNodeFiles(arguments);
   viewer->setSceneData( loadedModel.get() );
   viewer->run();
   delete viewer;

79f780d4b8 Fixed the compute of the extents/bounding sphere 2009-08-27 19:25:23 +00:00

9ea43a31c6 From Ross Anderson, "Symptom: The computation of TerrainTiles containing only image layers (no elevation layer) is incorrect. The resulting bounding sphere will always have a radius of zero.
The fix is to remove the call to bs.expandBy(v) and compute the radius directly. I believe this call was intended to be bs.expandRadiusBy(v), but it is superfluous when the radius is computed directly."

20ad246896 Added new virtual reseveElements, setElement, getElment and addElement methods to DrawElements
to make is easier to write code that can work on DrawElementUByte, UShort or UInt.

Changed the osgTerrain::GeometryTechnique so that it automatically chooses 
the use of DrawElementUShort or DrawElementsUInt accordining to the size of the tile.

39cecd2a72 From Philip Lowman, "Here's the promised cleanup of the OSG's CMakeLists.txt files for the src/ folder. I'll submit the others separately.
Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.

IF(${OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX} STREQUAL "quicktime")
was changed to
IF(OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX STREQUAL "quicktime")

44d144997e Added prelimnary KdTree data structure and automatic kdtree build support

4d60d73eca Reorginized the TerrainTile/TerrainTechnique dirty mechanism so that TerrainTile
now holds the dirty flag and enables/disables event traversal in response dirty
being set/unset.  This allows terrain to be automatically updated in response
to Terrain scale and sample ratio changes.

1519d0d546 From John Vidar Larring, "Added vertical scale as a property of osgTerrain::Terrain. Lets you configure vertical scale when initializing the terrain model. E.g:
osgTerrain::Terrain* terrain = findTopMostNodeOfType<osgTerrain::Terrain>(model.get());
  if (!terrain)
  {
      terrain = new osgTerrain::Terrain;
      terrain->addChild(model.get());
      terrain->setVerticalScale(2.0f);
      model = terrain;
