Adding vectors and applying rotation matrix using quaternion

[Duthomhas]

I am unsure about your data structures, because choice of structure makes a huge difference when doing this kind of thing.

Also, you need to learn more. Google around “affine transformations”.

I do not follow, provide an example

¿the bounding box? ¿axis aligned?

> I only know that rotation matrix using quaternion should be applied in the process
I fail to see why
also, ¿rotation matrix or quaternion?

> Also I should not that vector normalization operation will be done too before this.
¡great! ¿what for?
