Re: [osg-users] to draw landscapes beginning from a matrix
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,
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

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?

Re: [osg-users] to draw landscapes beginning from a matrix
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.

Re: [osg-users] to draw landscapes beginning from a matrix
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 case.
Robert.

Re: [osg-users] to draw landscapes beginning from a matrix
thanks for the satisfactory answer. 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 first in 2 dimensions (to color of white the smaller altitude and of black the greatest altitude), then to represent her in 3 dimensions. the purpose is to draw a volcanic ground for the simulation of castings of it washes. can you help me to understand as I must proceed? do you have some example of use of osg::HeightField and osg::Terrain? thanks in advance Aurora Restivo - From: Jean-Christophe Lombardo [EMAIL PROTECTED] http://gmane.org/get-address.php?address=jean%2dchristophe.lombardo%2dAYb5Cdd1jaQ%40public.gmane.org Subject: Re: to draw landscapes beginning from a matrix http://news.gmane.org/find-root.php?message_id=%3c47A1E355.4000707%40cstb.fr%3e Newsgroups: gmane.comp.graphics.openscenegraph.user http://news.gmane.org/gmane.comp.graphics.openscenegraph.user Date: 2008-01-31 15:03:49 GMT (4 days and 3 minutes ago) 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 (http://www.openscenegraph.org/projects/VirtualPlanetBuilder) jcl aurora restivo wrote: Hi!

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. http://www.vterrain.org/ Kind regards, Stephen. On Jan 31, 2008, at 9:32 PM, aurora restivo wrote: Hi!
