Hi stephan,
Nice, this totally took care of the Carbon referencing issues. I ran into a
couple of Cocoa related linking errors but only because I forgot to link to the
cocoa framework. Just a heads up for people following this path.
Thank you!

Hi paul,
Your description sounds right.
And yes the name clash with the fbs plugin was just an assumption after doing a
string search in the sources.
In terms of wrapping the plugins (eg: 3ds) in a namespace. I am not sure how
this would be done without breaking code. I feel like I just know

Has anybody compiled ffmpeg sucessfully to work with osg-2.8.3-rc2? When

everything from scratch. I have a feeling though the ffmpeg

I have a linker problem with the latest rc2 that I did not have with 2.8.2.

Hi,
I am trying to move to imageio and cocoa but am still unclear how to do this.
I just downloaded the 2.8.3-rc2 and build everything fine with imageio and
cocoa enabled. Only when I try to use the new libs with my apps I get a linker
error that indicates that Carbon is still configured:
If you switch your xcode-projects to gcc 4.0
the current 2.8.x source builds fine for 10.4 on Snow Leopard.
Nope, switching to gcc 4.0 does not make any difference for me. And BTW there
is no 10.4 SDK on snow leopard.

It's an install option when installing xcode.

I think I have solved the issue. It turns out that if I simply set a render bin
index on all my nodes that contain an osgText, things work as expected.
Surprisingly I don't need to set the osg::StateSet::OVERRIDE_RENDERBIN_DETAILS.
I would assume this is normal behavior. I think my main error

hey paul,
I needed to apply the patches for building osg against either SDK. It's not
exactly clear to me which change in Snow Leopard makes this necessary. Even
with the same xcode, gcc, and 10.5 SDK the osg 2.8.2 does not

So after some contemplation I am pretty sure I want to use the painter's

Hey Paul, Jeremy,
So, text is in the transparent RenderBin. Hmm that makes sense. I was
hoping there is simple explanation. I guess I could use depth testing. The

algorithm to determine the z position. It would mean to layer the

Thanks Erik,
Seems like the attachment did not come through on the forum. I got it
now and it's very helpful. Updating the Atomic file got rid of some
problems.
I am still banging my head at compiling on Snow Leopard. I must have tried
12 different configurations so far, 64 and 32 bit both
yes! success! You rock!
I can finally compile osg on snow leopard! What's better I can compile it in
any configuration I need to.
To recap, I needed to apply two fixes to the sources. First erik's Atomic
patch:
Code:
/* -*-c++-*- OpenThreads library, Copyright (C) 2008 The Open Thread
For completeness here is another patch I needed for building a
cocoa-based osg 2.9-svn with sdk 10.6.
in DarwinUtils.mm there are a couple of 'ID' that should be 'id' like in
-(void) show: (ID) data;
-(void) hide: (ID) data;
should be

Hi Eric,
Thanks for the hints. I was able to build osg for the most part now (i386,
10.5 sdk). I did not figure out why the int32_t typedef was missing
though. I simple changed it in line 70 of the Atomic header file to singed
long int. This did the trick for building osg with xcode.

Hi,
I have been doing some image stuff lately. JPEGs and PNGs load right but
BMPs are upside down. Is this a feature or a bug?
At the moment I am doing this for remedy:

if(filename.substr(filename.length()-3) == bmp) {
hey ulrich,
I am not sure I understand. I am loading a bmp and use it as a texture on a
quad. I use the same texture coordinates for various image types but only the
bmp displays upside down.

Granted that different image types store pixels differently I would still
assume that the image loader should nevertheless be consistent across different
image format. I guess this is an assumption that depends how low-level one
approaches pixel data.
So I record it is not a bug in the image
Thanks Robert,
It turns out that USE_OSGPLUGIN is working fine for osgdb_png and
osgdb_jpeg. I was simply not aware that I had to link againg libpng.lib
ang libjpeg.lib. I though since I compiled osg statically all the support lib
symbols are therefore in the osgdb_png/jpeg files.

Hi,
I am currently using osg statically and cross-platform. I have been pretty
happy with how it worked out but have recently run into problems with
certain plugins. Freetype works fine but png or jpeg does not with VS2008.
I do the usual USE_OSGPLUGIN(png); and am also setting the path to
Hi,
I am pretty experienced with C++ but ran into the Config header file problem a
while back as well. When you build OSG yourself it is created by the install
phase not the build phase. So you run into this problem if you do one of the
following:
- forget to run the install phase
- use the

I finally got it working on Linux. Took me a while to understand the Makefiles

by cmake for osgstaticviewer. Backtracking from there basically made me
realize that
the order in which the libs are listed in the gcc call matters. Is this for

Thanks for your answer.
It's actually not that complicated. jonim8or compiled osg for mingw and posted

Thanks Stephan, you answer was very helpful. After some headbanging I have it
working seemingly flawless. Here is the code for reference:
Code:
osg::Vec3d rayIntersectWithXYPlane(float x, float y, osg::Node* widget) {
// flip mouse y axis
y = ofGetHeight() - y; //important
So far so good. The culling works as expected. I can now define a custom active
invisible area and the picking works with it. Unfortunately it did not quite
tackle my problem with dragging.
The question have now: How do I manually intersect a ray with the x/y-plane of
geode?
The problem I
So I found some code for intersecting a line with a plane.
What I am missing is how do I translate the mouse pointer
coordinates into a line expressed in local coordinates?

Hi osg crew,
Learning osg has been really interesting and the documentation got so much

How do I add invisible (always culled) geometry to a geode that can be picked?
What I want to do is control the active area independently from that
I think I just found some code that would do what I want. Let me know if there
is a better way of doing this both in regard of the custom active area and the

So I found this in osgManipulator but I belive I could use this code
independantly of it. The idea is to add a cull callback
