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

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

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? Robert. On Wed, Feb 27, 2008 at 11:46 AM, aurora restivo [EMAIL PROTECTED] wrote: Hi! I have used the example of osgterrain but,

I need to get the terrain as in the figure that I send you, but without visualizing the skirt. Aurora Robert Osfield ha scritto: 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. El Thursday 21 February 2008 11:38:29 aurora restivo escribió: Hi Robert, I apologize for the trouble, but I don't understand of what file it has need the example

Yes, but the file .cpp needs a file to be performed. What's this file? Thanks Aurora Alberto Luaces ha scritto: From the location where you installed OSG source code, look at the examples/osgterrain directory. You will find osgterrain.cpp. El Thursday 21 February 2008 11:38:29 aurora

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

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

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

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 Robert Osfield ha scritto: Hi

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

Hi Aurora, You code is going off on the wrong track. Don't use ShapeDrawable here at all, don't try returning a osg::Geode. You should be returning the osgTerrain::Terrain, this is the node you should be concentrating. Please look at the osgterrain example. Robert. On Feb 20, 2008 12:48 PM,

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. Aurora Restivo

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

Hi, You should have look to the osgshape example source code (http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgshape/osgshape.cpp) jcl This footnote confirms that this

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

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

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

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

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! I have necessity to draw
