Function: computeMeanCurvature()

function computeMeanCurvature(geometry): Float32Array;

Defined in: src/utils/curvature.ts:18

Compute mean curvature for each vertex of a mesh.

Uses the umbrella operator (uniform Laplacian) as a fast approximation: H ≈ |v - mean(neighbors)| with sign determined by the vertex normal.

NOTE: This is only meaningful on folded (pial) surfaces. On inflated or flat surfaces, curvature will be near-zero. For those cases, load pre-computed curvature from the original folded surface.

Parameters

geometry

SurfaceGeometry

The surface geometry to compute curvature for

Returns

Float32Array

Float32Array of mean curvature values per vertex
