Hi Everyone,
I have a question about using the RBF3D Transformation with the TPS function. My expectation is that when I set up this function using P0 and P1 points, that P0 points are mapped to the exact location of homologous P1 points. I've taken care of any alignment / scaling / orientation outside of AnyBody.
I have set up a warping of the Pelvis STL (TLEM2.1) using point homologies I created outside AnyBody. But in this list are the hard coded position of anatomical locations (ASIS, PT, Hip center) taken from ModelJointParameters.any and ModelParameters.any.
I have located these anatomical points on my target (P1) pelvis. However, when I load the model, the anatomically defined control points in P0 do not map to their P1 defined locations. This manifests in distances between the anatomical locations that are different than in the P1 points (on average ~1.6mm)
As an additional issue, I have marker drivers that are defined relative to some of these anatomical locations (namely hips). But their positions seem to be offset by the difference between the P0 origin point and homologous location in the P1 points.
Any guidance would be greatly appreciated.
