WasmGPU.createTransform().traverse

Summary

WasmGPU.createTransform().traverse visits the current transform and all descendants using depth-first pre-order traversal. The callback runs on the current node first, then each subtree in child order. Use this for hierarchy-wide updates, bulk tagging, and debug export. Traversal is synchronous and executes entirely on the calling thread.

Syntax

WasmGPU.createTransform().traverse(callback: (t: Transform) => void): void
transform.traverse((node) => {
    // visit node
});

Parameters

Name Type Required Description
callback (t: Transform) => void Yes Function invoked once per visited node in depth-first pre-order.

Returns

void - This method does not return a value.

Type Details

type TraverseCallback = (t: Transform) => void;

Example

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

const root = wgpu.createTransform();
const a = wgpu.createTransform().setParent(root);
const b = wgpu.createTransform().setParent(root);
const c = wgpu.createTransform().setParent(a);

const visited = [];
root.traverse((node) => visited.push(node.index));
console.log(visited, b.parent === root, c.root === root);
