Hi,

I wonder if someone could share a bit on the topic of creating models (to be used in OpenGL) using some modeling tool.

I tried Blender to create some simple stuff and wrote a wave-front parser. I spent some days on this, but Blender is quite complicated. Maybe I just need to put more time into it...

Is this the way forward? Is it possible to configure blender to export directly into a custom format? How does Collada come into the picture?

What are my options? I feel a bit lost here and would appreciate some guidance.

Thanks
/P

In short, it depends on what you're needs are.


Is it possible to configure blender to export directly into a custom format?

Use the integrated Python scripting. Check this out:

Also, a few of the above-linked posts talk about doing this.

And an OpenGL wiki entry on this, just for completeness:

In games (like for example battelfield), how are the worlds/maps created? :-)
