Class: CrosshairManager

Defined in: src/CrosshairManager.ts:15

Manages a 3D crosshair (three orthogonal lines) that can be positioned at a vertex on a surface mesh. Supports selection and hover modes.

Methods

show()

show(
   mesh, 
   surfaceId, 
   vertexIndex, 
   options?): void;

Defined in: src/CrosshairManager.ts:39

Show the crosshair at a specific vertex on a mesh.

Parameters

mesh

Mesh

surfaceId

string

vertexIndex

number

options?

CrosshairOptions

Returns

void

---

hide()

hide(): void;

Defined in: src/CrosshairManager.ts:81

Hide the crosshair and clear tracking state.
