How to use vue-3d-loader

If use in global, insert code in entry file：

/* vue2 */
import vue3dLoader from "vue-3d-loader";
Vue.use(vue3dLoader)

/* vue3 */
import vue3dLoader from "vue-3d-loader";
createApp(App).use(vue3dLoader).mount('#app')

If non-global use, insert code in your vue files:

import { vue3dLoader } from "vue-3d-loader"; // The vue3dLoader in {...}

Use tags in your components<vue3dLoader></vue3dLoader>

<vue3dLoader
  :height="200"
  :showFps="true"
  :filePath="['/fbx/1.fbx', '/obj/2.obj', '/gltf/3.gltf']"
  :mtlPath="[null, '/obj/2.mtl', null]"
  :backgroundColor="0xff00ff"
></vue3dLoader>

API

Attributes

prop	type	default	description
filePath	string | array	-	File path, supports multiple files to be loaded together, note: If each file corresponds to a material, you need to set the material mtlPath as an array. The same is true for image textures, which need to be set to textureImage as an array
mtlPath	string | array	-	.material path, supports multiple materials to be loaded together, set this parameter to an array, you must set filePath to an array
textureImage	string | array	-	jpg/png texture, if is array, filePath must be set to an array
width	number	-	width
height	number	-	height
position	object | array	-	object position
rotation	object | array	-	rotation coordinates
cameraPosition	object	{ x: 0, y: 0, z: 0 }	camera position
cameraRotation	object	-	camera rotation
scale	object | array	{ x: 1, y: 1, z: 1 }	scale the model
lights	array	[{type: "AmbientLight",color: 0xaaaaaa,},{type: "DirectionalLight",position: { x: 1, y: 1, z: 1 },color: 0xffffff,intensity: 0.8,}]	lights is array, type AmbientLight and DirectionalLight
backgroundColor	number | string	0xffffff	background color supports number/hex/rgb. like 0xffffff/#f00/rgb(255,255,255)
backgroundAlpha	number	1	Background transparency (range 0-1)
controlsOptions	object	-	control parameter OrbitControls Properties
crossOrigin	string	anonymous	Cross-domain configuration. The value is anonymous or use-credentials
requestHeader	object	-	set request header. example: { 'Authorization: Bearer token' }
outputEncoding	string	linear	The value is linear or sRGB. Renderer's linear is LinearEncoding, sRGB is sRGBEncoding (sRGBEncoding can restore material color better). Renderer's output encoding WebGLRenderer OutputEncoding
webGLRendererOptions	object	{ antialias: true, alpha: true }	WebGLRenderer options WebGLRenderer Parameters
showFps	boolean	false	show stats infomation
clearScene	boolean	false	clear scene
parallelLoad	boolean	false	enable/disable parallel load models (useful only for multi-model loading). Use this attribute, the process event will be unpredictable
labels	object	{image: "", text: "", textStyle: { fontFamily: "Arial", fontSize: 18, fontWeight: "normal", lineHeight: 1, color: "#ffffff", borderWidth: 8, borderRadius: 4, borderColor: "rgba(0,0,0,1)",backgroundColor: "rgba(0, 0, 0, 1)" }, position: {x:0, y:0, z:0}, scale:{x:1, y:1, z:0}, sid: null}	Add an image/text label and set image to display the image label. Set text to display text labels. Text styles can be set using textStyle. For examples, see the examples/add-label.vue file
autoPlay	boolean	true	auto paly animations
enableDraco	boolean	false	Load the Gltf Draco model, you need to enable Draco decryption. After the Draco decryption library is enabled, you need to download Draco decryption library and put it into the default directory assets. The default directory is assets/draco/gltf/. If you want to change the default draco directory, use dracoDir parameter. About draco and threeJS
dracoDir	string	assets/draco/gltf/	Draco decryption library default directory, you can modified it.
intersectRecursive	boolean	false	If true, it also checks all descendants. Otherwise it only checks intersection with the object.

Events

event	description
mousedown(event, intersects)	mouse down, intersect: currently intersecting objects
mousemove(event, intersects)	mouse move, intersect: currently intersecting objects
mouseup(event, intersects)	mouse up, intersect: currently intersecting objects
click(event, intersects)	click, intersect: currently intersecting objects
load	load model event
process(event, fileIndex)	loading progress, fileIndex: the index of the currently loaded model
error(event)	error event

Example

1. Load a 3D model

supports dae/fbx/gltf(glb)/obj/ply/stl models

<!-- fbx model -->
<vue3dLoader filePath="models/collada/stormtrooper/stormtrooper.dae"></vue3dLoader>
<!-- obj model -->
<vue3dLoader filePath="/obj/1.obj"></vue3dLoader>

2. Loading multiple models in the same scene

<!-- Load multiple models of different type, support for setting position, scale, and rotation for each model -->
<template>

8. Loader draco model

Need to download Draco repository storage with local static folder of your project, download url: https://github.com/king2088/vue-3d-loader/blob/master/public/assets/draco.7z

<template>
  <vue3dLoader
    filePath="/models/gltf/LittlestTokyo.glb"
    :cameraPosition="{ x: 10, y: 700, z: 1000 }"
