Hi Glenn,
Yes that surely helped. I looked at the osg file generated by vpb and didn't
see the ellipsoid model in there. Just didn't strike me that I would have to
take a different route.
P.S. I tried accessing the osgEarth website a couple of times last week but it
seemed as though it was do
I should add that the reason the marker dimension is being hardcoded into the x
axis because at this point I'm positioning the spacecraft along the Y axis. I
was considering creating in a way similar to this every time, then rotating it
to match the lander, but would be open to a more dynamic so

To a degree, yes.

Do this during the update phase.
It' usually not safe to do this while any traversal (like update) is running,

Hi,
I'm working on a tool that visualizes a spacecraft in orbit around a planetary
body. As it is set up now, the position of that spacecraft is given relative to
the center of the body as an x,y,z coordinate. What I'm trying to do right now
is set up a simple altimeter that looks essentially l
Hi,
Sorry if subject changed in previous topic. In my humble knowledge of
distributed rendering, i think scene graph must have some kind of mechanism to
sync frames to be rendered in each cluster (rendering machine). As your post
states , a socket communication can transmit the sync messages.
OSG doesn't prevent you from doing distributed rendering. If you have a copy of your scene graph on multiple machines and your app uses a socket or other mechanism to communicate, you have distributed rendering.

Thanks for the reply lwi.
The rest of the code is identical to the osgprerender example. The above
section of code is the only part I changed.
I tried setting the camera's clear color by changing the alpha value to 0.0f,
but it behaved just as if the alpha value was 0.5f, or 1.0f. In other word
Hi,
Thank you for teh fast response. Your answers are quite satisfying. Now that
you have mentioned about osgVisual, i took a look at the project and saw that
distributed rendering is possible.

Sanat,
The method won't work because your VPB database is not geocentric. It is
projected (UTM). A non-geocetric db won't have an EllipsoidModel.
Setting an EM won't work. The EllipsoidModel conversion methods only convert
between geodetic (lat/long) and geocentric.
The conversion works in osgEa
Hi,
I would like to add some new nodes into scene graph during runtime. Is it
possible somehow?
Thanks

Silver Lining is not F/OSS,
I'm fairly certain there's a way to create a window that's not visible, supported by all three major windowing APIs. I know that's not quite what your looking for, but it's an option.
I do agree with J-S, I think you need to have a context current to something. Since the calling app appears to al

In any case, to use FBOs you need a context, one way or the other.
