Hi Brad,
To benchmark, you can change the quality of the compression in
TextureUtils.cpp.
For the moment, the compression is set to nvtt::Quality_Production,
using nvtt::Quality_Normal you should have much better result. As I
remember from the nvtt documentation, nvtt::Quality_Normal is much
Hi Brad,
I just check the code, in fact it does not work when using --terrain,
only with --polygonal.
I am submitting a fix to Robert.

Hi Jean Sebastien,
I have removed the warning by putting the declaration of objectDeleted()
directly into the class definition. See attached file.
It seems to be a compiler bug. I love template :)

Hi All,
In order to compile on Windows with Wrappers ON, some exports are still missing
on osgPresentation::AnimationMaterialCallback and

avoid the need for an expensive scale operation, and also enable the support
under GLES and GL3 to work as neither have GLU.
As for the difference in behavior on your systems I can't explain.

Hi Robert,
It works now with my example on windows.
But i have a problem with my application, i am currently playing with
Texture2D::SubloadCallback to optimize my image data transfer, and also avoid
double buffering when using a drawing thread.
There is a small bug with your change and
it, but
in the end never did or need to it.
Since the method isn't used I've just removed it and updated the wrappers.
Could you do an svn update and let me know if things work fine.
Cheers,
Robert.

The osgViewerQt example does not take into account modifier key. So, the

I have changed the conversion between Qt event and OSG event to handle

you need some help.

I have tested the integration between Qt GraphicsView and OSG too.
To have better results, don't use drawBackground() to do OSG drawing but
