I thought there was a way to remove the makeCurrent(context) /
makeCurrent(null) calls inbetween the rendering of frames.
I believe there was a message of Robert about this feature.
Isn't it the case?

Hi,
Ok, after many googling (and stumbling around aimlessly) I've found a similar

Hi,
Can anyone help me on this!! The texture of the 3D object appears fine with an
Nvidia card and fails with an ATI card. I have attached two images to see the
problem.
Thank you!

Hi Craig,
Today I build OSG x64 bit with the fresh downloaded 3rdParty package V3, and
everything worked as expected.
Therefor I assume that your download is somehow corrupted or that your
decrompress tools are broken.
If anyone else have similar problems, please contact me. Otherwise I
Thanks Chris, Andreas, Gordon.
@Andreas.
However, if you want to extract a regular terrain height raster from an
OpenFlight database, I would say the best solution is to write an OSG
application that simply intersects vertically with the terrain at equal
distances and puts the result in
Hi Robert,
following your suggestions, i solved my doubts.
This is the correct code:

cnCylinder-addChild(cylinderModel);
groupCylynder-addChild(cnCylinder);
clipPlaneForCylinder=new osg::ClipPlane();
planeForCylinder=new
Hi Mukund,
I just meant that you could implement a spatial traverse over the
terrain bounding box with equal steps in X and Y, intersect vertically
with the terrain and put the resulting terrain heights in an image which
you can write to disk with one of the OSG image plugins implementing

I have to distort a scene to be consistent with the video that is diplayed

i have a new post regarding for setting osg::cone tip to (0,0,0) and scale my

I did some tests since that post and I finally have the distorted texture with

You build yourself a heightmap for a series of height queries. The
osgintersection and osgpick example provides and examples of how to do

You won't need a height map at all :-)

Hi Torben,
Thanks for checking that the download works. I am not sure what is going on
with my laptop then. I will try again today on my desktop computer when it
gets rebuilt. Which program are you using to uncompress the .7z file?
Thanks one again for your assistance.

Thank you!
The problem with the code was that I was not setting the matrix translation and
rotation correctly.
I was doing the following which was not working:

And the specs were always through and complete.
It's the versioning I had trouble with.

Hi Adrien
I've never actually done this but I have thought about it as I'll need it
eventually.
I think your best bet is to look at void BasicAnimationManager::update (double
time), that is where an animation is played through and were you can detect
that an animation is finished. Perhaps you
