Exporting EMPTY Objects From Blender

> That would be helpful for making animation keyframes and placing objects in games.

ABSOLUTELY. Any Help in this Department is greatly appreciated...

Math is a difficult subject to master. If we could just use Blender in this fashion that would be great.

I think using empties in Blender is a great idea. Here is my effort for 1.3.2


I've put the changes on google code at

Wow, thanks a lot for the help with my question zzajin! You rock!

Looking at the code you submitted zzajin, it looks like the empty object that is exported is the transform location, correct?
What about the transform rotation and scale. The rotation is the most helpful, in my personal opinion.

Thanks.

Yeah I can see rotation being of use now. I didn't realize it would mean anything since we are talking about a point. But indeed you can rotate them and I see you can set the display as single arrow which shows the z axis direction which would be a strong visual cue.

Scale would be easy to add too, but I'm having a hard time thinking of a use. Seems like if you want to add a trigger zone the bullet physics would be a better option. Perhaps as a spawn point, but instead of exactly at the point, you utilize scale to create a random area that a spawn could occur?


I added rotation to the code above: the exporter, sio2_empty.cc, and the exporter and the example are affected.

My main use for rotations would be to for different points of rotation for cameras.Thanks a lot for the rotation code. It's much appreciated!

Cheers

I just edited sio2_resource.cc. I found 2 missing edits.

Great thanks again zzajin!

hi, zzajin
thanks for your Empty code
I think the Empty object 's Scale is very useful, such as we can paint a icon picture on any party of the model , think about painting your image on floor with different size.
