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

[aurora restivo]

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

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)
