Hi!
I have used the example of osgterrain but, even if the skirt is not
visualized anymore,
now my terrain is flat (as in the attached figure).
besides the colors should be used with the gradations, from the tallest
altitude to the lowest.
how can I get these results?
Thanks
Aurora
Hi Aurora,
Do you actually need the Locator that takes you into geocentric
coordinates? I.e. are you looking for a flat earth projection or a
geocentric one?

From the location where you installed OSG source code, look at the
examples/osgterrain directory. You will find osgterrain.cpp.

Yes, but the file .cpp needs a file to be performed.
What's this file?
Thanks

Hi Aurora,
To assign the no data value do:
hfLayer-setValidDataOperator(new osgTerrain::NoDataValue(0.0f));
Also you shouldn't need a ShapeDrawable when you are using
osgTerrain::Terrain, but you will need to assign a TerrainTechnique
that will be used to render the terrain. See osgterrain
Hi Robert,
I send you the code with the new changes... unfortunately the result
doesn't change...
the plan around the terrain has not disappeared.
the object terrainTechnique that you have recommended me is necessary to
color the terrain?
Thanks
Aurora

returning the osgTerrain::Terrain, this is the node you should be
concentrating. Please look at the osgterrain example.

Hi!
the image jpg in enclosure, is the result of the terrain that I have
drawn beginning from the matrix of the altitudes.
I would want to know if a way exists for not visualizing the quotas
equal to 0.
the source code is found in the file morfologia.txt
Thanks in advance.

Hi Aurora,
I think what you are looking for is the osgTerrain::ValidDataOperator
that you can attach to your elevation layer via
Layer::setValidDataOperator(operator);
In include/osgTerrain/ValidDataOperator you'll find the NoDataValue
subclass which is probably what you want to use in your

Hi,
You should have look to the osgshape example source code

I have tried to study his solution but it is difficult for the lack of
complete documentation.
I can try to explain better the problem:
I have a matrix of altitudes 410 X 296, I would want to represent her

You might either
* build an osg::HeightField
(http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01227.html)
and draw it with an osgTerrain::TerrainNode node with an
osgTerrain::HeightFieldLayer as an elevation layer
* or use VirtualPlanetBuilder
Hi Aurora,
From the generality of your question I would suggest you first go
look at the Virtual Terrain Project web site..
It's an awesome source of info.

Kind regards,
