Thanks aftacer!
There is a lot to learn about this stuff that takes time to learn. I have to
admit that I'm learning too. But that's why I do this stuff. The best way I've
found to learn this stuff is to get the into book (is free), learn as much from
the examples at code as you can. If all
Hi David,
First off, let me say that I'm a complete rookie when it comes to OSG but I was
experiencing ( as far as I can tell by your post ) the same exact thing quite
some time ago. I resolved my problem with some help from people on this list
so the least I can do is provide you with that
Greetings All!
I'm going to try testing this problem on a simplified model.
Basically, I have this shell I built to test my experiments in IK dynamics
using OSG.
I can also use it to test this problem.
FYI: I'm bringing this basic model with me to SIGGRAPH next week to possibly
demo.
So,
Hi David,
As you seem to resolved the issue I'll not dive in too much further,
but the following comment from jumps out as needing a reply:

Hi Robert,
The reason that I did this, was basically to echo the performer version of the
viewer that this will replace - I used the osghud example as a guide.
In the old performer code, they used multiple views because in some cases the
data would be so bad that plains would fly through the
Hi David, Tom,
Are you enabling transparency? - for example by:
Code:
osg::StateSet* state = node-getOrCreateStateSet();
state-setRenderingHint( osg::StateSet::TRANSPARENT_BIN );
state-setMode( GL_DEPTH_TEST, osg::StateAttribute::ON );
That last one should probably have been:

Aye, that's what I meant. I just copied/pasted the wrong line of code. Thanks
for pointing that out J-S. I always turn on GL_DEPTH_TEST anyway to be safe,
even though on is the
Yea That was it!
Now if I can only fix my original problem, but that I figured there was a quick
answer for! Makes me wonder what other GL settings I need to activate that I
forgot! Humm!! :?
Thanks!

FYI Figured out how to build a phatom globe to hide objects after it gos behind
the earths horizon. Now I can pan across the earth and my layered objects
disapear behind the earth as it should.

Yea maybe I should have put more of the code up so you can get a better view of
the whole thing. The issue is posting code on a public site like this requires
approval from my boss (the Navy) - even though it's unclassified info, getting
approval to show it can be a pain sometimes!
Hi,
One other thing while I'm at it!
When I set the drawing color on a Geometry lets say:
I have a color
Code:
osg::Vec4d color = osg::Vec4d(1.0f,0.0f,0.0f,0.5f);
I set the color of the used in the Geometry. For intance, I have a Geometry
called myCircle, when I set myCircle color, I use

In this example I have alpha set to 0.5f but I don't see what I drawing

Hi David,
There could be couple of reasons, but I can't work out from your post
exactly what is not working and where so I'll provide some general
suggestions as to what might be wrong, but given I don't know what the
actual problem is I can't provide any suggestions as to how one might
fix it.
Hi,
things you could try or check:
* is the bounding sphere OK?
* turn on/off displaylists and call -dirty()
* make near/far use primitives, like so:
viewer.getCamera()-setComputeNearFarMode(osg::CullSettings::COMPUTE_NEAR_FAR_USING_PRIMITIVES);
viewer.getCamera()-setNearFarRatio(1e-6);

Greetings All!
I hate to come up with another stupid one, but I've been banging my head with
this one!
One of the displays I doing has an ellipsoid globe appearing and above that, I
have some Overlay lines (what we call MOA lines) or marker lines. I have them
drawn above the globe and from a
