You might want to set the READONLY flag on the referenced SV, but that's a minor safety nitpick. Otherwise that seems fine. The memory management is problematic, though. Nothing is going to free that Vector3 for you. For a leaf type like that, though, you can probably get away with defining an Ogre::Vector3::DESTROY that frees the memory. I am wrapping something very similar (involving a proprietary C++ 3D graphics framework), and I took a different approach for my equivalent to your Vector3 (for which I use OpenInventor types, so that would be SbVec3f). I convert it to an array ref of three values. I also convert the other way. More recently, I've started blessing the reference into a vector package that overloads various mathematical operators. But it's all exposed directly at the Perl level, which saves having to go through another layer of accessors to get at the contained X, Y, and Z values. (It also avoids the memory management issue.)
