New Slerp option in Blend Shapes H15

Say you have two primitives which have intrinsic transforms like VDB primitives, sphere primitives, or tube primitives. Then you can blend these transforms in a more intuitive/expected fashion than the usual component-wise blending of the transforms as matrices.

Thanks Edward, and I thought this could be an option for blending rotations and have it behave like one expects. I tried it here with polygons turned into packed primitives and tried to blend rotations, it gave me some kind of arc blending but not 100% correct.

Looks OK to me. You are transforming single packed primitive along shortest (thus linear) path from one position to another (90 degree rotated).

SLERP maintains blending that way it's correctly blended, so you will not get scale/skew deformation during blending. And this is happening. You can see that dimensions of that primitives remains constant during blending.

When you turn off SLERP you will get scale deformation during blending so it will get shortest in the middle of the blend animation.

 

Don't forget that pivot of the packed primitive is in the middle.

 

If you expect to see arcs in the trails, be sure that you have correct pivot. Move the grid center 0.5 unit along X axis so it is at the origin. And then in the Assemble sop set Pivot Location to Origin.
