Hi Martins,
the writer is still a work in progress so I suspect that feature hasn't yet
been implemented. Talk to Sukender (http://sukender.free.fr/) to find out if
it's on his to-do list, if not then your help will be appreciated ;)

Hi osg-users,
Is it possible to change the way the data file path list is stored ? I mean
OSG use a double ended queue to store new data file path, isn'it more
efficient to use a list instead ?
In my case i'm adding new file path from a list of new model added to my

Cześć,
Replace it with 720.f/568.
I'm doing this on float but in other place. I set this to this code only for
demonstration.
I known what is being wrong. Angle at lookAt function must be in degrees and
multiple by viewport matrix is also ok.
And now evrething is ok.

Thanks

Hi Glenn,
Right now the OSG just supports updating an entire VBO when used via
the osg::Array class.
You could implement your own subrange copying by getting the VBO
handle yourself and then manually doing the copying that you need to
do.
The other alternative would be to look at how one might

HI Arthur,
Projective textures such as done in the OverlayNode knows nothing
about depth so can't do what you require as is. The best you could do
is just decide yourself what whole objects have the texturing on them
by enabling/disable the texture modes for them, or excluding them from

You can't expect others to dive into huge amounts of code and know

In my application, I created a texture set to the screen size. Ortho camera has

I found the cause of missing textures. If you have a Stateset with
textures applied to a Geometry node, it generates an fbx file with
textures. If the Stateset instead is applied to the Geode parent of the
Geometry, you get no texture. Unless Sukender has some suggestions on
how to tackle
