Class: ConnectivityLayer

Defined in: ConnectivityLayer.ts:125

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.

Accessors

order

Get Signature

get order(): number;

Defined in: layers.ts:343

Numeric initialization hint used when this layer first enters a stack. Runtime ordering is owned exclusively by LayerStack.

Deprecated

Use LayerStack.setLayerOrder() or LayerStack.moveLayer() after the layer has been added. Runtime writes are ignored.

Returns

number

set order(order): void;

Defined in: layers.ts:347

Parameters

order

number

Returns

void

Methods

fromMatrix()

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

Defined in: ConnectivityLayer.ts:214

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

Parameters

id

string

matrix

   config?
): ConnectivityLayer;

Defined in: ConnectivityLayer.ts:271

Create from CSR (Compressed Sparse Row) data. Extracts upper-triangle entries (j > i) to avoid duplicates.

Parameters
