WasmGPU.createAnnotation.toolkit().pickAtAndCommit

Summary

WasmGPU.createAnnotation.toolkit().pickAtAndCommit runs a pick query and immediately feeds the result into selection/annotation commit logic. Behavior depends on current mode (marker, distance, angle, idle) and staging state.

Syntax

WasmGPU.createAnnotation.toolkit().pickAtAndCommit(x: number, y: number): Promise<AnnotationRecord | null>
const record = await toolkit.pickAtAndCommit(x, y);

Parameters

Name Type Required Description
x number Yes Canvas-space X coordinate in CSS pixels.
y number Yes Canvas-space Y coordinate in CSS pixels.

Returns

Promise<AnnotationRecord | null> - Resolves to a created record when a mode transaction completes, otherwise null.

Example

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const scene = wgpu.createScene();
const camera = wgpu.createCamera.perspective({ fov: 55, aspect: canvas.clientWidth / canvas.clientHeight, near: 0.1, far: 1000 });
const toolkit = wgpu.createAnnotation.toolkit({ scene, camera, canvas, autoBindPointerEvents: false });

toolkit.setMode("distance");
canvas.addEventListener("click", async (event) => {
    const rect = canvas.getBoundingClientRect();
    const record = await toolkit.pickAtAndCommit(event.clientX - rect.left, event.clientY - rect.top);
    if (record) console.log("created", record.id, record.kind);
});
