Re: [osg-users] [3rdparty] change ocean height
Hi JS ok I have updated osgOcean from the trunk and tried the new setOceanSurfaceHeight function. It is working well. Except that I have no node reflections in the water ? Did you try it ? In my 1st pic you can see the ocean and a cow at altitude 0, the reflection is great.

Re: [osg-users] [3rdparty] change ocean height
Hi Sebastien,
I think this is because the reflection matrix used by the reflection
FBO doesn't take into account the change in height and is still trying
to reflect the scene across the origin.
I don't have much time to give to osgOcean at the moment so if you
need a fix urgently you should have a go yourself.
It should be pretty easy to sort out, just modify the
_reflectionMatrix variable in OceanScene when the
setOceanSurfaceHeight is modified to reflect across the new ocean
plane.
void setOceanSurfaceHeight(double height){
_oceanTransform-setMatrix(osg::Matrix::translate(0,0,height));
_isDirty = true;
}
If you get to it before me, send in the code and I'll merge the fix.
Cheers.
Kim.

Hi again, If you get to it before me, send in the code and I'll merge the fix. I'll do this right away. Give me a few minutes. Done and committed to osgOcean SVN trunk. I also added a command line parameter to the oceanExample so that you can experiment with the ocean surface height. So for example I tested with: oceanExample cessna.osg.(0,-15,90).rot.(0,200,115).trans --oceanSurfaceHeight 100 (which uses the cessna.osg model from OpenSceneGraph-Data and positions it 115 meters in the air, and places the ocean surface at 100 meters) Hope this helps, and sorry for forgetting the reflection matrix when I added ocean surface height control...

[osg-users] Compel a camera (using MatrixManipulator) inside a sphere
Hi,
Here's my problem.
I have affected a nodetrackmanipulator to a viewer and a callback to the camera.
I want is to compel my camera inside a sphere.
So, in the callback method operator() I get the nodetrackmanipulator,
get the position matrix mat from it using getMatrix().
Then I compute the lenght of the position the camera (this is done in the
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv) method) :
[code]
osg::Matrixd mat = _nodeTrackerManipulator-getMatrix();
double length = mat.getTrans().length();
if (length sphereRadius)
{
osg::Matrixd newMat;
newMat.identity();
newMat.setRotate( m.getRotate() );
newMat.setTrans( 0, 0, 0);
_nodeTrackerManipulator.setByMatrix( newMat );
}
[/code]
The problem is that the display result is wrong. The camera is not at position
(0,0,0).
I have also try using setByInverseMatrix but nothing.
What should it done to update the position, rotation nodeTrackerManipulator
(matrixManipulator) ?
Thank you.
[/code]

[Image: http://img246.imageshack.us/img246/9285/sanstitre1yg.jpg ] If you lower the cow or lower your point of view you'll see the reflection becomes clearer.

[Image: http://img297.imageshack.us/img297/836/sanstitre2hs.jpg ] Yep, that was it. Simple fix. Sorry about that. Note that the reflections are clipped to a plane, but the ocean surface is not a plane (which is the whole point of osgOcean... :-) ) so there are some points where if the waves are really high the reflection will be missing on part of it. It's either that or have reflections popping up behind objects as you saw, so it's a lesser of two evils situation... And please don't apologize about reporting bugs, we have to find these bugs! I don't use these features in our other projects here, so other users like you are the only source of testing... If you want you can always try to fix them and send us the fixes, but I will never say Oh no, not another bug report... Damn, osgOcean's software quality is getting way too high... I wish these bug reports would stop and the bugs would just stay there... ... :-) J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I'm curious too, I'm not sure if they're fully implemented. In VPB the vector (build and forest outlines imported from shape files) support is limited to databases build that use polygonal meshes rather than osgTerrain::TerrainTile. VPB now defaults to generating databases with osgTerrain::TerrainTile's as they are more compact and more flexible as they allow runtime decimation of data as well as terrain modifications, but it doesn't yet have support for handling vector data. To use the polygonal build you'll need to use --polygonal. I would like to see support added to osgTerrain::TerrainTile to allow us to provide polygonal outlines and fixed points of interest that the tesselation will honour, once this is in place we'll be able to get the shapefile support in VPB rolled out to all combinations. I should add that I'm not the author of the shapefile support in VPB, so I can't answer in too much about it's implementation.
