Hello everyone,
after some headaches I have found a solution to a compile problem in
a program using osgGA::GUIEventHandler and linux/input.h (neccesary
for make work an old joystick model, not possible to be modified).
Here is an exctract of the code which throw
Hi Christian,
The usual way to avoid pollution of 3rd party #defines to to make sure
that the polluters are included after the ones that are effected. If
this isn't possible then to #undef the problem #defines.
Another possible route would be to simply use a non polutting headers
and lib for
Hi,
I have a problem with my osgexp on 3dsMax.
Latest version for 2012 (1.0.1)
When I create my .IVE, it appears with a strange texture.
(right the right texture and left after converting.)

Hi,
Yes I am experiencing the same. Does anybody know when the site will be

Hi everybody,
I just tried to run scivi (a 3d scan tool), which depends on OSG. Everytime I
get this error:

~/Downloads/scivi$ make
g++ -c -O3 -Wall -I Data/Libraries/libPoisson/include -I Data/Libraries/vcglib

Hi,
I am trying to integrate the Parallel Split Shadow Map (PSSM) algorithm into
my current project. I've noticed that the algorithm utilizes the fixed pipeline
as it only incorporates a fragment shader.
However, my project requires me to write a custom Vertex shader as well. When
I do
Hi
I've had same problems with 1.0.1, dont have any good solution, but you can
export model with external texture files and then use osgconv to embed them,
then it'll look ok.
Also, if you open max file with some old model (which was used with pre 1.0.1
exporter) clear it, merge with new one
I had been building terrain complexes using osgdem using both the -d and -t
flags to combine elevation and textures. This works great when I have
relatively low resolution. I am now running into scenarios where I am using 1
meter lidar elevation data and want the maximum number of levels.
Hi,
I'm using FRAME_BUFFER_OBJECT as render target to render into an FBO.
I would like to generate mipmaps for this FBO...
How can I do this ? Is there any function like myFBOTexture-buildMipMaps()
that I can call in my FBO camera's post-render callback ?
Thank you!
Cheers,
Aurelien
Just use the setUseHardwareMipMapGeneration to the texture object you
bind to the FBO

Does that mean mipmap generation is fully automated ?
If I try to access to FBO's mipmaps from a shader program, mipmaps will be
available ?
Are the mipmaps always generated (even if not used) or are they only generated
on demand when they are used ?

Hi Aurelien,
if you ask the hardware to create the mipmaps for you (
setUseHardwareMipMapGeneration() ) they are generated automatically.
Otherwise you can write on a given mipmap level yourself, see the level
parameter of Camera::attach() method.
I believe that if you use
A user of our OSG application is experiencing some random crashes on his
machine. To investigate the problem I provided the osgviewer application and he
keeps experiencing the same problem. By the way, if a crash occurs, then it
occurs at the very beginning and no OpenGL windows (context?) is
In some cases, that bad visualization is due to the Gamma/LUT Correction. Don't
know if this is also your case, but try disabling the Gamma/LUT Correction:
from Rendering menu, Gamma/LUT Setup..., Gamma and LUT tab and finally uncheck
the Gamma/LUT Correction option.
Hope this helps.

Hi Laurens and Sergey,
Thank for your answers, the problem was what Laurens brought up - I had
compiled (recopiled osgexp also) with VC 2010. I recompiled all (including
osg files) with 2008 and no more errors J

Thanks Chris,
I actually compile osgEarth and osgGIS last week and played around with them a
bit thinking I may go in that direction. I was having trouble getting the vpb
driver to work properly and the osgEarth vpb driver page even says:
If at all possible, you should run osgEarth against the
Ethan,
VPB is typically used for creating statically built pre-runtime
databases. osgEarth is more of a dynamic model and paradigm. I would use
either one or the other depending upon your needs. Based on what you
want to do, I agree with Chris that osgEarth would probably be the
better fit.
I think the best thing then is for me to get my scenarios up and running with
osgEarth and see just how much a speed hit I'd take using it vs VPB. Plus the
project I'm working on may ultimately be better served by hosting the data on a
server and creating a web interface for the user, and
All things considered, I think that would be a wise direction to go in.
If you do any database performance profiling between osgEarth and VPB,
feedback on this would be informative...
