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: SpineData.

Compatible data

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 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.
