Scene.traverseVisible

Scene.traverseVisible¶

Summary¶

Scene.traverseVisible iterates only over meshes with visible === true. This avoids manual filtering when applying per-frame logic to rendered meshes only. Traversal order is insertion order within the mesh list.

Syntax¶

Scene.traverseVisible(callback: (mesh: Mesh) => void): void
scene.traverseVisible(callback);

Parameters¶

Name	Type	Required	Description
`callback`	`(mesh: Mesh) => void`	Yes	Function executed once per visible mesh.

Returns¶

void - No value is returned.

Type Details¶

// No additional descriptor expansion is required for this signature.

Example¶

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const scene = wgpu.createScene();
const a = wgpu.createMesh(wgpu.geometry.box(1, 1, 1), wgpu.material.unlit({ color: [0.9, 0.3, 0.2] }));
const b = wgpu.createMesh(wgpu.geometry.box(1, 1, 1), wgpu.material.unlit({ color: [0.2, 0.8, 1.0] }));
b.visible = false;
scene.add(a).add(b);
scene.traverseVisible((mesh) => mesh.transform.translate(0.02, 0, 0));
