I created terrain from srtm30 hgt file and georeferenced (using gdal_warp with
srs WGS84) google earth images. I got the terrain but the altitude seems not
included in terrain. When I opened the osg file, I could see altitude is less
than 1 which is not the actual. I don't know why? Can

Hi Wojtek,
You probably know this but if not it may be other option for you. One
can define restart index that works as terminator for triangle/quad
strips (check GL_NV_primitive_restart extension) . So in practice
multiple triangle strips can be separated by restart indices and put
into one
Hi Tim,
That sucks. I'll take a look.
OK, let me know what you find out. I was pretty surprised the optimizers
would go out of bounds, as I've used them on a variety of models without
problems (as I bet you have, and many others too).
Thanks in advance,

Hi Sergey,
I've used gDEBugger tool for rendering optimizations, it have modes that turn
off some features of rendering so you can determine what impacts framerate most
(like it have modes which turns off all lights(fixed pipeline vertex lighting
impact), replaces all textures with 2x2
Hello Mukund,
r.makeRotate( rot += 10, osg::Vec3( 1., 0., 0. ) );
The angle should be in radians. I think your code above assumes it's in
degrees.
What are you expecting to see BTW? The camera might rotate around the
scene's origin (since your view matrix has no

Thanks for the reply.
So in your case you simply add the Geode to the
MarixTransform node and then the geode and all it's children then are
transformed by it
So, you mean this is fine?

Hi Tim,
I've found that that problem happens because the attribute arrays are
shared among several Geometry objects. The fix is simple, but I haven't
submitted it yet because the results of INDEX_MESH are still not great
on the sphere object, and I have a different idea for how to approve that.
Hello J-S,
Thanks for the reply.
Why do you insist on using

Absolutely. i did not realize it first since i was used to using glut. But now
i realize the osgviewer is much easier and efficient.
So, im currently using the method
Well, the model is as such. So, there seems to be no problem.

Hi.
I wonder if there is a way for loading materials/statesets from
external osg-file.
I´ve tried to use ProxyNode in osg file to load a model but I would
like to just load a stateset or a material.
Best regards.

Hi Paul,
Thanks for this explanation about identifying nodes. Actually we also
implemented a node identification using child index...
However I did not spot metadata related classes in osgWorks. Well, ok, I just
had a very quick overview... Can you tell me where to look at?

Hi Sukender,
I'm not sure what you mean; I need to see an example. The IndexMeshVisitor
doesn't work with BIND_PER_PRIMITIVE attributes and bails if it finds any.
If the number of vertex coordinates doesn't equal the number of texture
coordinates, that's a big bug. Normally the number of indices

Am I suppose to use another version of freetype?
AFAIK no, it's a universal-lib (i386 + arm) and had worked in the past.
FYI, I recently setup a FreeType Xcode project for iOS to support
SDL_ttf. It is based on a blog entry written by Alfred Rossi. This
might be helpful if you need to rebuild
