Derive a stable anatomical curvature underlay

Source: R/render_surface_rgba.R
anatomical_curvature.Rd

Averages computed curvature over mesh neighbors before display. This is an anatomical texture operation: neither coordinates nor statistical overlays are modified. Prefer a native curvature/sulcal metric when available.

Usage

anatomical_curvature(geometry, iterations = 5L)

Arguments

geometry

Matching folded (usually white) [SurfaceGeometry].

iterations

Number of adjacency averaging steps, including the vertex itself. Zero returns [curvature()] unchanged. This is not an FWHM in mm.

Value

Numeric anatomical metric with one value per vertex.
