Hi everybody,
I'm tyring to compile your tutorials on the wiki (can't send the links yet,
this is my second post). I'm having some strange "Segmentation faults" that
appear some times, disappear other times. I think it may be because these
examples are rather old (8~9 years).
I'm using the lat
Hi, all
Why the parameter _lock_azim_while_panning is set to lock in a camera heading
when performing panning operations in OSGEarth EarthManipulator. I think this
can lead to the problem of steering when rotates parallel to the north or south
poles. My OSGEarth version is 2.7.
Thank you!

learning.

Have you lost the ability to read in 2017?
Book's are another resource at your disposal, they don't take away
from the rest of the resources.

A bit clarification, openscenegraph.org used to be the old site while
we transitioned to using Joomla on a new server, during transition the

Hi Rodrigo,
Not sure which tutorials are you following, but if you are looking at
trac.openscenegraph.org yes, they are totally out of date. Probably we
should think in finally remove the trac. All the resources are now in
www.openscenegraph.org. Also and a part from the books which are a great

Hi,
On the upside, I've been studying the workings of OSG and looking at the source
code really helps. However, my glTexSubImage2D continues to have zero effect on
its code. I'm doing this via a operator StateAttribute callback on the texture,
binding it, then trying to write pixels. I've also

Hi,
I'll post a pretty print I know you guys like colors.

The callback is attached with `texture->setUpdateCallback( new Painter() );`

Hi Johny,
By default, OSG will run graphics operations in a separate thread so trying to
do OpenGL calls from the main thread will not have an effect. Update callbacks
are always invoked from the main thread. Try using a DrawCallback on a Drawable
or Camera instead which will be invoked from th
Hi Robert,

Right. But you also has a link at Documentation | Platform Specific | Linux. I
thought everything platform specific would be there, but it wasn't, so I went

Mingxia,
That is by design - if you lock your camera azimuth (to north-up for
example), you will be unable to rotate past the poles. You can disable the
feature by calling
EarthManipulator::getSettings()->setLockAzimuthWhilePanning(false).
Hope this helps

Hi,
In linux we are using osg::Text to display some chinese characters.Then
we find the osg::Text looks a little blur when the size of characters is
small.Or,the Black characters seems a little gray when the character size is
small.I have setFontSolution(128,128),it not help.

HI Lv,
osgText::Text renders into a 3D scene using OpenGL, which is quite
different than Qt rendering to a 2D window where font resolutions can
exactly matched to the pixels on screen, so you can't really compare
the two.
osgText::Text itself doesn't implement anti-aliasing, anti-aliasing is

Hi.
I currently work on a set of tutorials to build and use OSG for several
platforms (desktop, mobile, web), however, they will be only available in
2-3 months.
I'll keep you updated.
