Here is a little something about 3D
Green-> easy
Red-> don't ask x)
I forgot the Mid transition between Side and Point, it's possible to make it.
In the orange position, the camera focal length can make the edge of the blade wider than it seems. You know, when the pointy part is too close to the cam, there might be a distorsion. Same thing for the "point" view.
Mid positions can vary between 0 and 2
2 is smooth enough IMO, but it's long to do.
