For those who deal with terrain in OSG, what tool do you use to create trees as
textured transparent billboard to be loaded by OSG? I'm just wondering what's
the best native format for creating the trees.
Examples:
FLT -- OSG -- IVE
or
3DS -- OSG -- IVE
or
VRML -- OSG -- IVE
...
Thanks,

I'm wondering how to go about layering manipulators so that by default the
terrain manipulator is used except for a small corner of the screen where I
want a custom manipulator (like Google Earth's compass manipulator). Is there
already a mechanism for doing something like this?

Speaking of billboards...other than OSG/IVE is there an existing file format
that can save billboards with transparencies so they appear correct once loaded
in a osgViewer-based app?
I'm new to terrain viz and would like to use the billboards for doing trees,
but they always appear opaque
For those interested. I finally finished my little osgDem UI and it turned out
pretty good. My clients are happy because they don’t have to deal with the
command line. Actually, I find it easier to use too since it automatically
validates long and complicated argument strings.
You can see a
I've used Collada-DOM before for another project but for some reason cannot
seem to provide the correct include directories for building the COLLADA
plugin. I develop on Windows.
Does OSG expect any special directory structure or environment variable? What
parameters should be put in CMake
More speciffically: what entry is expected under COLLADA_LIBRARY?
Thanks,

I'm a newbie too and have had the same problem applying the MFC example to my
own app. The problem was that wasn't giving a complete path. Use szPathName
instead of szFilename from the MFC file dialog.
Another way is to have the directory containning your data in your PATH
environment

Hi,
The MFC example seem to have changed lately. I suggest you grab the latest
version from SVN and compile that. I'm not usre this will fix your problem,
but worth try anyway.

As a recent newbie myself, here what I suggest you read:

Antoine,
So how do I make sure that the osgdb_ecw.dll plug-in gets called instead of
GDAL? As it is, osgDem just stops (crashes actually...). I am not looking
foward to recompiling GDAL ;(

I meant that OSG plugins are called in sequence, each plugin is trying

Thanks for the advice. Actually, I have already started saving osgDem
