9526a3c35d Maded TerrainTechnique::setTerrainTile(..), addNeighbour(..), removeNeighbour(..) and containsNeighbour(..) virtual and public to enable implementation of TerrainTechnique that act as a facade to actual TerrainTechnique implementations. 2018-03-29 11:38:53 +01:00

4b4e02e45b From Hartwig Wiesmann, "in the files Image, Observer and TerrainTechnique unused parameters exist resulting in a couple of compiler warnings (depending on the compiler settings though).
The attached patches comment out the unused parameter names.

c6c26d5d44 Change Terrain so that it subclassed from CoordinateSystemNode.
Implemented new update scheme of GeometryTechnique to avoid potential threading issues.

Added Terrain support to .ive.

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;
}"

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.
