Class: ConnectivityLayer

Defined in: src/ConnectivityLayer.ts:52

Geometry-based layer that renders connectivity edges between surface vertices as lines or instanced tubes, with optional node spheres at endpoints.

This layer does not participate in color compositing; it renders its own THREE.js objects that are attached to the surface mesh.

Methods

fromMatrix()

static fromMatrix(
   id, 
   matrix, 
   config?): ConnectivityLayer;

Defined in: src/ConnectivityLayer.ts:142

Create from a symmetric NxN weight matrix. Extracts upper-triangle entries (i < j) where weight !== 0.

Parameters

id

string

matrix
