[Blender and OSG]

Hi

Maybe Blender can export into .3ds or .obj file ?

Post by Jean-Baptiste Authesserre
Hi,
I would like to use blender to create my 3D models. Is that possible to
use blender files .blend with osg?
I compiled by myself osg by using Cmake for the configuration of the
Visual studio project. I found no mention about blender during this
configuration step.
After the compilation, there exist in the generated plugin folder the file
osgdb_3ds.dll, which I suppose allow me to use 3DSMAX file. But I don't find
anything about blender.
Could anybody help me?
Best regards,
Jean-Baptiste.

Thank you for these quick answers. Blender can export in .3ds file, but it
is the use of this export function I would like to avoid. In fact I observed
that if I save my 3D objects in blender format and then open the file
.blend, there is no problem, my objects have kept the transform properties
(dimension...) I set. But if I export to 3Ds and then I import the generated
3ds file with blender, the dimension of my object have changed. I don't know
why. That's why, I would rather use .blend file, because i need specific
and realist dimensions for my OSG application.

Try the blender-osg exporter posted earlier

http://projects.blender.org/projects/osgexport/

It has worked well for me (even though I have not used it that much). It
preserves the hierarchy, but you need to take care when you do some
things (like applying textures) to make sure they survive the export and
come out correctly in OSG.

Here is my collection of links when I had to explore the world of
Blender-OSG exporting. :)

Note: I am *not* a modeler. I just play one on TV. ;)

Hope this helps,

J-S

I was aware of blender -osg export, see

http://projects.blender.org/projects/osgexport/

not sure if it is the most up to date

No one except the Blender developers know what a .blend file is, and
even they can't really even explain much about it. I've tried many times
in the past to wrap my head around its binary format, but it's seriously
the very definition of "moving target." Besides, if you asked the
Blender developers in IRC, they'd say trying to load a .blend file in
your engine is really a bad idea (I've been the recipient of this kind
of scolding :)).

Your best bet is to use the .osg exporter, which works quite well. Even
better, you could get a copy of the modified one in the AnimTK project,
which has a few small bug fixes here and there that will (eventually)
get propagated back to the main one.

Some people from the flightgear comunity use an exporter to ac3d.
In theory the osg exporter can do a better job due to various limitations of
the ac3d format. But I have never tried one of them. So you might just
try ...

Hello,

I made positive experience with the OBJ export. Vertices, normals, texture
coordinates and materials are exported and can be correctly loaded by OSG.

Benjamin

Thanks a lot! Has anybody an Idea of which 3D file format can be used with
OSG (other than 3DS)? Because blender can export in many formats... Else I
would test your suggestions...

Hello,

have a look at the list:
http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/Plugins

For example OBJ works as already stated before.

Our best experience has been to export either as either obj or osg (using
osgexport). The osgexport blender plugin has the advantage of handling
animations within a single .osg file, obj handles anims as well, but
produces one .obj file for each timestep.
