Hi Diana,
I find it pretty convenient to use
Code:
getCamera()->setViewMatrixAsLookAt (const osg::Vec3 &eye, const osg::Vec3
¢er, const osg::Vec3 &up)
for setting up the view matrix, it was one of Robert's suggestions but I
thought I'd re-emphasize it. Vec3 "eye" will be the position you're
Thanks alot Robert. I try to teach me some math on my own now, but your answers
were really helpful.
@ulrich
I did include I just missed to write it in my Post.

Hi Diana,
I'm afraid I don't have the time to write up a full tutorual on maths
of setting view matrixes and matrix maths, the topic has been covered
lots of time by the community so I'd recommend you have a look through
the archhives.
As a quite note, I'd mention that in OpenGL and the OSG the v
Yeah, I'm just seeing the blue background. And yaeh im struggeling with the
math to set up my matrix.
I set it up like this:
while(!viewer.done())
{
osg::EllipsoidModel convert;
convert.convertLatLonHeightToXYZ(lat, lon, height, x, y, z);
osg::Vec3 pos(x, y, z);
osg::Matrixd matrix

What do you mean, doesn't display your scene. What do you see? Just
the default blue backgroud?
Did you set your view matrix to look at the scene? If you don't have

Thanks Robert,
but when I try
viewer.setSceneData(loadedModel);
viewer.realize();
while(!viewer.done())
{
...
viewer.frame();
}
it doesen't display my scene. viewer.run() works fine.

Hi Diana,
If you are controlling the camera from a user defined path or
simulation then you are best to not attach a camera manipulator to the
viewer and just set the viewer's master camera directly yourself. If
you do try to set the camera's view matrix yourself but still have a
camera manipualt
Hi,
I'm trying to write something like a flightsimulator for simulating a sensor.
For this I have some world data for my scene.
Now I'm trying to create a camera. But the camera doesen't look to where I want
it to look at. I get the following values
- the position in lat[deg], lon[deg] and he
