Hi,
i got this little piece of code, with which i wanna display a heightfield. I
read that for performance reasons one should use terrainTile and add the
heightfield to it, but i dont get it to display in the viewer? i know the
osgTerrain example, but i find it is too big for starting. i hope someone could
help me?
Here is the small code:
int main() {
osg::ref_ptr<osgTerrain::TerrainTile> terrainTile;
osg::ref_ptr<osg::HeightField> hf;
osg::ref_ptr<osgTerrain::HeightFieldLayer> hfl;
osg::ref_ptr<osg::Group> group;
osg::ref_ptr<osgViewer::Viewer> viewer;
group = new osg::Group();
terrainTile = new osgTerrain::TerrainTile();
hf = new osg::HeightField();
hfl = new osgTerrain::HeightFieldLayer();
viewer = new osgViewer::Viewer();
hf.get()->allocate(100, 100);
hf.get()->setXInterval(10.0);
hf.get()->setYInterval(10.0);
for(unsigned int r=0;r<100;++r)
{
for(unsigned int c=0;c<100;++c)
{
hf.get()->setHeight(c,r,400);
}
}
hfl.get()->setHeightField(hf.get());
terrainTile.get()->setElevationLayer(hfl.get());
group.get()->addChild(terrainTile.get());
viewer.get()->setSceneData(group.get());
viewer.get()->realize();
viewer.get()->run();
}
Thank you!
Cheers,
Thomas
