createMesh#getBounds

Summary

createMesh#getBounds is an alias for getWorldBounds() and returns a fresh world-space bounds snapshot. It includes mesh transforms and initialized morph weights but not skin deformation.

Syntax

Mesh.getBounds(): Bounds3
const result = mesh.getBounds();

Parameters

This API does not take parameters.

Returns

Bounds3 - Bounds structure containing axis-aligned box and bounding-sphere data.

Type Details

Bounds3

type Bounds3 = {

    boxMin: Vec3;

    boxMax: Vec3;

    sphereCenter: Vec3;

    sphereRadius: number;

    empty: boolean;

    partial: boolean;

};

Bounds3 Fields

Name Type Required Description
boxMin Vec3 Yes Minimum corner of the axis-aligned bounding box.
boxMax Vec3 Yes Maximum corner of the axis-aligned bounding box.
sphereCenter Vec3 Yes Center of the associated bounding sphere.
sphereRadius number Yes Radius of the associated bounding sphere.
empty boolean Yes Whether the bounds contain no geometry.
partial boolean Yes Whether the result omits geometry whose bounds could not be determined.

Vec3

type Vec3 = [number, number, number];

Example

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

const geometry = wgpu.geometry.box(1, 1, 1);
const material = wgpu.material.unlit({ color: [0.9, 0.6, 0.2], opacity: 1.0 });
const mesh = wgpu.createMesh(geometry, material);
const result = mesh.getBounds();
console.log(result);
