Hi there.
The journal reads
Houdini 14.0.215: The Blend Shapes SOP and Time Blend SOPs now have an option to use spherical linear interpolation when blending primitive transforms.
Thanks to this change, some time warps with packed primitives that were badly deforming the copies now work seemingly well.
Can anybody explain what´s this and what´s going un under the hood. Wikipedia hints this is related to quaternion rotations but I could certainly take a specific explanation to what´s going on there.
