Hi GuiYe,
do you want a smooth elevation transition from area with DEM to area without
DEM?
Then you have several possibilities:
a) modify your DEM sources to a image format, and at the border of your DEM
region blend the gray values smoothly into the null value
b) modify your viewer to
Ciao,
So, looks like we have a decision, cool!
To summarize, if I've got it right, for every texture map in the material we
will find a description string like the following (assuming we use the | as a
separator):
Diffuse|Unit_0|c:\program files\whatever\file.png|80
where:

HI Camile,
You simply need to walk back from of the end of the

to use.
If you want to see an example of highlighitng picked items have a look

Thank you!

Hi,
You use ASTER data? Am I right that ASTER is public available? I played 2
years ago with the ASTER data as it was initially released. It has great
resolution, but it had also lots of artefacts. Do you use raw or somehow
corrected ASTER data? - As you can see, I'm on the never ending quest

Hi Guys
Been following this with interest. Having a method to know what map type is
in what texture unit will be great. Regarding the normal mapping, is there
any chance of getting the exporter to also generate tangent vectors (either
from max or using osgUtils). Would be ace if you could also

Yep - it's not real stable right now.
But I got the unit tests up and running on my copy now - (1 out of 5 passes) so
I'll work on fixing them and post a new version.
I also noticed when it's run from blender it saves the file to Scene.osg in the

Hi,
Thanks Stephan, you actually replied to my original message. I have since
edited it and suggested to concentrate on the leak issue. The other issue I
have is still under investigation and yes, the code I had originally posted
(too fast) to illustrate the second issue was incorrect ;)
Thank you!
How about strm 90m DEM? Do you make terrain in earth as I do?

Hi,
The second issue I had was that by design OSG doesn't assume the bounding box
of a drawable should be recalculated when setting a computeBoundingBoxCallback
up on the object.
In other words I was expecting Drawable::_boundingBoxComputed to be set back to
false when setting the callback.
Hi,
we have a performance problem with the nVidia 400 series.
But first:
Our software is a 3D physics simulation. We use ODE for the physics. Qt is

You are absolutely right! I had mistakenly assumed that the description

If the new meta-data system is going to support all osg::Object derived

The exporter applies the material statesets to the osg::Drawable object,
which does not support description strings. I can add the description to

Hi Vincent,
I have been using Visual Studio 2010 and fstreams and OSG DLLs with no issues
at all. The only possibility is you are compiling with incompatible compiler
options between OSG and your other library. All files must be compiled /MD(d)
and of course compiled with Visual Studio 2010.
