C++ (Cpp) LOD::getNumRanges Examples

Example #1

File: MRTShaderInstancing.cpp Project: whztt07/osgVegetation

		void apply(osg::LOD& lod)
		{
			// find the highest LOD:
			int   minIndex = 0;
			float minRange = FLT_MAX;
			for(unsigned i=0; i<lod.getNumRanges(); ++i)
			{
				if ( lod.getRangeList()[i].first < minRange )
				{
					minRange = lod.getRangeList()[i].first;
					minIndex = i;
				}
			}

			//remove all but the highest:
			osg::ref_ptr<osg::Node> highestLOD = lod.getChild( minIndex );
			lod.removeChildren( 0, lod.getNumChildren() );

			//add it back with a full range.
			lod.addChild( highestLOD.get(), 0.0f, FLT_MAX );

			traverse(lod);
		}

Example #2

File: LOD.cpp Project: 151706061/OpenSceneGraph

// _rangeList
static bool checkRangeList( const osg::LOD& node )
{
    return node.getNumRanges()>0;
}
