示例1:
bool
TileNode::shouldSubDivide(osg::NodeVisitor& nv, const SelectionInfo& selectionInfo, float lodScale)
{
unsigned currLOD = _key.getLOD();
if ( currLOD < selectionInfo.numLods()
&& currLOD != selectionInfo.numLods()-1)
{
osg::Vec3 cameraPos = nv.getViewPoint();
float radius2 = (float)selectionInfo.visParameters(currLOD+1)._visibilityRange2;
return _surface->anyChildBoxIntersectsSphere(cameraPos, radius2, lodScale);
}
return false;
