My goal is to replace the rotations and scalings with translations,to change the orientation with translating with special vectors.
On the first picture,I translate the b bone over 3 frames with 90 degrees.The b'1 vector is generated after the first frame,the b'2 vector after the second,and the b' vector is generated at the end.
On the second picture,instead of rotating it,I translate the b vector with v1,v2,and v3 vectors.At the end of frame one,there is a b'1 vector,what is described as b + v1,and is equal with the b'1 vector on the first image.
The second frame add v2 to b'1,instead of rotating it with 30 degrees,and the third adds v3 to b'2.
And at the end,b vector is rotated with 90 degrees over 3 frames without using rotations.
The goal is to find these v1,v2,v3 vectors,and replace the rotations with translations with them.
