Spine Mesh Curvature
=====================

Summary
-------
Computes curvature-related metrics from distance volumes for each anatomical mesh in a `SpineData`, and colorizes meshes for visual analysis (e.g., curvature QA or thresholding decisions).

See also: :doc:`SpineData <../SpineData>`.

Compatible data
----------------
- Requires: :doc:`SpineData <../SpineData>` with vertebra meshes.

Output
------
- Updated meshes with per-vertex colors encoding the selected curvature metric.

Key parameters
--------------
- `resolution` (mm): Isotropic spacing of the distance volume used for curvature computation.
- `sigma` (mm): Gaussian smoothing applied to the distance volume.
- `meshColorData` (enum): Curvature metric to visualize (see controller for available values).
- `meshColorRange` (%): Symmetric value range mapped to colors ([-range, +range]).

Workflow
--------
1) Provide a :doc:`SpineData <../SpineData>` with meshes.
2) Choose the curvature metric and color range.
3) Compute; inspect colored meshes.

Tips
----
- If meshes are not colored, verify the `SpineData` contains mesh geometry.
- Adjust `Mesh Color Range` to avoid saturated color maps; increase smoothing if noise dominates.
