Rotate to certain orientation using VOP SOP or VEX

[windwolfx23]

 Hi guys~

how can I use VOP SOP to do a rebuild fx: move fragments back to their original position and orientation. I managed to get back to the original position, but have no clue how to do the rotation.

Use spherical linear interpolation, you will need to extract the transformations, you can use matrix3 to quaternion and do the slerp that way or simply build your own axis and angles in vops

Thank you mightcouldb1~ I watched the video, it's great  but my project got multi-solver involved, and I have to use a sop solver to do the rebuild , the function "slerp" sounds the right one to do the trick , but I havn't got it work, here is my vex codes:

if(@Frame>50)

{

    float time_form = fit(@Frame,50,200,0,1.0);

    @orient = slerp(@orient,@ini_orient,time_form);

}

I just want the @orient  value blend to @ini_orient value in 150 frames and start from frame 50.
