about
nx_profile_fit.nx -- cross-section shape priors derived from a supplied mesh.
Triangle-plane segments are grouped by X projection, then fitted to an ellipse
and dimensionless angular radial ratios. This is not full contour segmentation.
The procedural emitter controls final dimensions; the ratios remain derived
from the source mesh and retain its provenance and applicable obligations.
Extraction alone establishes neither anatomical fidelity nor permission to reuse.
Infinigen reference-profile lofting is a related research approach, not a claim
of implementation equivalence or validated physical accuracy.
nx_profile_fit <oracle.nxmesh> <out.dat> [step_permil] [canon_out.dat] [part_id]
Optional part_id declares a single-part oracle and bypasses body band grouping.
