Qt/3d model save / export

[nconway]

I see QGLAbstractScene has a loadScene() method for loading models, but are there provisions or planned provisions for a model save/exporting to one of the supported sceneFormats?

If not, if this was something I wanted to do, what would be the most Qt/3d way go about it?

For instance, if I wanted to make a file converter to convert from .OBJ to .3ds could I do that?

Only some ideas to convert files from obj. to 3ds.

I think it is difficult to convert a obj-file to 3ds, because the structure is entirely different.
Especially of 3ds. The .obj-files you can read with a normal texteditor.
So if you want to create a converter it would be recommendable to study the structure of 3ds, which you can find here:

"tutorial2":http://www.spacesimulator.net/wiki/index.php?title=Tutorials:3ds_Loader

You can check your result by using blender, if your own viewer isnt working correctly yet.

To the matter of QGLAbstractScene i cant say anything but maybe this might be of any help:

"QtQuick3D scene node geometry":http://developer.qt.nokia.com/forums/viewthread/12453

But you have probably seen it yet.

Thanks for the great links,

I guess the example of the file converter might not be totally appropriate for what I want. I really want to be able to create geometry in my code and save/export it to obj format, or some other format that could be opened by a Blender or Maya. The third link seems helpful to that end, but it looks like there are no built in export facilities.
