示例1: main
// main program.
int main(int argc, char** argv)
{
// set up the viewer
osg::ArgumentParser arguments(&argc,argv);
osgViewer::Viewer viewer(arguments);
// make sure we have a shape file.
std::string shapefile;
if ( !arguments.read("--shapefile", shapefile) )
return usage("Missing required --shapefile argument");
// install a motion model
viewer.setCameraManipulator( new osgEarth::Util::EarthManipulator() );
// create a visible imagery layer:
ImageLayer* imagery = createImageryLayer();
// create a masking layer using the shapefile:
ImageLayer* sharedLayer = createSharedLayer( shapefile );
// create a new map and add our two layers.
MapNode* mapnode = new MapNode();
mapnode->getMap()->addImageLayer( imagery );
mapnode->getMap()->addImageLayer( sharedLayer );
// make a custom color-filter shader that will modulate the imagery
// using the texture from the shared layer. (Using a ColorFilter
// will apply the effect to just one layer; if you want to apply it
// to all layers, you can just create a VirtualProgram and apply that
// the the mapnode->getTerrainEngine() state set.)
ColorFilter* filter = new MyColorFilter( sharedLayer );
imagery->addColorFilter( filter );
// done!
viewer.setSceneData( mapnode );
