osgconv --compressed-dxt1 cow.osg cow.ive
due to different handling of the extentions in osg 3.4 and up.
attached is a zip with the files:
OpenSceneGraph\applications\osgconv\osgconv.cpp
This file is valid for svn branch and stable3.4."

To select standard OpenGL 1/2 build with full backwards and forwards comtability use:
./configure
make
OR
./configure -DOPENGL_PROFILE=GL2
To select OpenGL 3 core profile build using GL3/gl3.h header:
./configure -DOPENGL_PROFILE=GL3
To select OpenGL Arb core profile build using GL/glcorearb.h header:
./configure -DOPENGL_PROFILE=GLCORE
To select OpenGL ES 1.1 profile use:
./configure -DOPENGL_PROFILE=GLES1
To select OpenGL ES 2 profile use:
./configure -DOPENGL_PROFILE=GLES2
Using OPENGL_PROFILE will select all the appropriate features required so no other settings in cmake will need to be adjusted.
The new configuration options are stored in the include/osg/OpenGL header that deprecates the old include/osg/GL header.
I added a new tag to p3d called forward_touch_event_to_device and renamed the existing forward_event_to_device to forward_mouse_event_to_device. This new tag will transmit touches to the virtual trackpad as touch events. I added the MultitouchTrackball to the p3d-app so zooming and moving a model remotely should now work, if you use forward_touch_event_to_device. I kept (and fixed) forward_mouse_event_to_device for background compatibility, so old presentations works as in previous versions, without the ability to zoom + scale. of course.
forward_touch_event_to_device needs some more testing, (e.g. with image-streams and keystone, afaik there’s no support for touch-events...) but for a first version it works nice.
"
* a new command-line-option to present3d and a new option to the p3d-plugin to suppress any found <env> tags
* a new command-line-option to present3d to forward mouse-events via osgGA::Device (defaults to off) so we can test the interface-files with present3d better
* I added a new attribute forward_to_devices for click_to_event to forward the event to all attached devices instead of handling the event locally. This will fix the annoyance with the new interface-files when toggling polygon-mode or switching light on/off.
Here’s an example:
<click_to_event forward_to_devices="true">0x72</click_to_event>

a few modifications to these files:
- applications/present3D/Cluster.cpp
- src/osgDB/FileUtils.cpp
The changes are needed to fix a few platform specific things such as the
absence of stat64, int/socklen_t differences, etc... and are in the same
line as Linux, Apple and FreeBSD specific checks.
I have attached the modified files; the original patches to 3.0.1 are
also visible here if you find it more convenient:
http://dl.wolfpond.org/dports/graphics.osg/dragonfly/patch-applications_present3D_Cluster.cpphttp://dl.wolfpond.org/dports/graphics.osg/dragonfly/patch-src_osgDB_FileUtils.cpp
With these changes, osg 3.0.1 is able to be built and packaged on DragonFly
whereas it previously failed to compile."
New methods osg::Geometry::containsDeprecatedData() and osg::Geometry::fixDeprecatedData() provide a means for converting geometries that still use the array indices and BIND_PER_PRIMITIVE across to complient
versions.
Cleaned up the rest of the OSG where use of array indices and BIND_PER_PRIMITIVE were accessed or used.
