8fc287c1b7 Added asUpdate/Cull/EventVisitor and asCamera/asDrawable to osg::Object and usage of these within the code base to avoid dynamic_cast<> usage. 2016-01-20 17:49:10 +00:00

afbf20eba9 First step of refactoring the osg::Program management in osgTerrain::GeometryPool for better performance by placing default osg::Program and shader defines on a single StateSet below the osgTerrain::Terrain

f13dd3d75d Added a fix for a multi-threading bug that occured when TerrainTiles were accessed via the Terrain::_updateTerrainTileSet that were being deleted at the same time by the DatabasePager thread. 2012-08-31 16:00:55 +00:00

a53308f7e8 Gunnar Holm, "After upgrading from 2.8.3 to 3.0.1 we experienced a lock in the Mutex 
functionality when using Terrain::setVerticalScale. This was caused by
the following call sequence resulting in a lockup:

void Terrain::setVerticalScale(float scale)
  CALLS    dirtyRegisteredTiles();


void Terrain::dirtyRegisteredTiles(int dirtyMask)
 SETS LOCK    OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
 and CALLS (on every tile)   setDirtyMask(dirtyMask);


void TerrainTile::setDirtyMask(int dirtyMask)
 CALLS _terrain->updateTerrainTileOnNextFrame(this);


void Terrain::updateTerrainTileOnNextFrame(TerrainTile* terrainTile)
 SETS LOCK   OpenThreads::ScopedLock<OpenThreads::Mutex> lock(_mutex);
******* PROBLEM - since lock has already been set! ********


The suggested fix submitted changes from using Mutex to ReentrantMutex.

526b39060c From Brad Christiansen and Robert Osfield, "I have added the new function as suggested. The change was made against trunk from an hour or so ago. I haven't tested the performance yet (and probably won't get a chance till next week) but I have checked my terrains still work. I defaulted the equalization to off as I thought this was best until we can look into why there is the performance hit. 
", note from Robert, tweaked the names and enabled the code path.

6798fe4c25 From Brad Christiansen, "To build OSG using Visual Studio 2010 Terrain.cpp requires #include <iterator>. This is a very common fix when using 2010 due to changes in Microsoft STL.

80389a4a13 Re-organized the access of the mutex in Terrain to avoid deadlocks, and temporarily switched off the update of the neightbouring tile boundaries within the GeometryTechnique::generateGeometry method, again to avoid deadlocks. 2010-06-16 12:46:16 +00:00

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.

5fe30854dd From Jason Beverage, "Attached is a fix for getTile in the Terrain class. It should be checking for itr == _terrainTileMap.end() instead of itr != _terrainTileMap.end()." 2008-10-06 08:48:44 +00:00

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;
  }
  viewerWindow->setSceneData(model.get());
