Hi,
I don't have any other suggestions than to use a GL debugger to make
sure nothing is going to CPU or to try the new CUDA functions in osgPPU
or your own code. I remember something in the GL to CUDA stuff bugging
me, but cannot remember the details. AFAIR something was converting from

Hi,
I suggest you manipulate your input data using gdal tools and then just
stick the results into vpb. Trying to align and crop data in vpb is
difficult.

Yes, its a first simple test to figure things out. I'll test to have the lowest

How would I implement a quadtree for this?. I mean, I know the algorithm and so

Good Day,
A very Happy New Year to All!
Are there any thoughts regarding this inquiry that I'd posted a couple of weeks
ago?
To further clarify, I guess what I'm asking is:
Is it possible to specify that only the highest LOD be paged in (ignoring all
other LODs), or alternatively is it

Yes, that's literally the keyword that mac libraries understand that will be
translated to the appropriate path.
There are others, I believe, but that's the only one I use.

Thank you for the suggestion. I feel like I'm missing something
still. Is there an Optimizer feature or something that combines
Arrays for you? Or did you write a bunch of custom code that

PSSM is probably the best choice for large scene.
PSSM technique have been fixed in osg 2.9.9 or 2.9.10 for minor bug.
If you didn't see shadow in your scene with this technique, this probably
a bug in your code.
Take a look to osgshadow example to know how use it. You have to run
Hi Lucie,
You can fill an osg::Geometry by computing yourself the vertices position.
take a look to osggeometry to know how to use and fill osg::Geometry.
You can also use an osg::Shape combined with osg::ShapeDrawable
to draw a half sphere. Take a look to osgshape to know how to use osg::Shape
Thanks, I'll have to determine if upgrading to osg 2.9.10 is feasible
for my project. Or perhaps osgShadow could be backported to osg 2.8.3?
After writing that email, I also discovered osgShadow::StandardShadowMap
and osgShadow::LightSpacePerspectiveShadowMap, both of which work quite

This seem that you run 64bit osgversion executable and use 32bit libosg.so
library, or vice versa.
You have to choose one version to install on your computer, or put the
directory containing the
right version of osg library in first place of your PATH environment
variable
