or

yarn add 3d-loader

How to use 3d-loader

If use in global, insert code in entry file：

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

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

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

import { vue3dLoader } from "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>

Attributes

const filePath = './models/tree.obj'
/* or */
const filePath = [
  './models/tree.obj', 
  './models/building.obj'
]

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

const fileType = 'obj'
/* or */
const fileType = ['obj', 'gltf']

File type is the 3d model(s) file extension, is used for filePath(http url) without file extensions. Is used together with filePath. If filePath is an array, this parameter must be an array.

const mltPath = './models/tree.mlt'
/* or */
const mltPath = [
  './models/tree.mlt',
  './models/building.mlt'
]

Material path, supports multiple materials to be loaded together, set this parameter to an array, you must set filePath to an array

const textureImage = './texture/tree.jpg'
/* or */
const textureImage = [
  './texture/tree.jpg',
  null, 
  './building.png'
]

jpg/png texture, if is array, filePath must be set to an array

]

Enable/disable parallel load models (useful only for multi-model loading). Use this attribute, the process event will be unpredictable

const labels = [
  {
    image: "", 
    text: "", 
    textStyle: { 
      fontFamily: "Arial",

  }
]

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

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

If true, it also checks all descendants. Otherwise it only checks intersection with the object.

Set enableDamping to true to enable damping (inertia), which can be used to give a sense of weight to the controls.

The damping inertia used if enableDamping is set to true. dampingFactor

true，only enable vertical rotation of the camera

true，only enable horizontal rotation of the camera

Value only support MeshStandardMaterial and MeshBasicMaterial. For ply model. MeshStandardMaterial doc.MeshBasicMaterial doc.

Enable or show axes

Example

1. Load a 3D model

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

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

    support for setting position, scale,
    and rotation for each model
-->
<template>
