uniapp微信小程序3D XR-FRAME

1.在pages.json中配置展示页面（style中添加下面：）

"usingComponents": {

          "xr-start": "../../wxcomponents/xr-start"

        }

2.manifest.json中配置mp-weixin

"setting" : {

            "urlCheck" : false,

            "postcss" : true,

            "es6" : true,

            "minified" : true

        },

        "usingComponents" : true,

         "lazyCodeLoading" : "requiredComponents",

3.pege文件同级依次建立文件wxcomponenrs/xr-start/(index.js、index/json、index/wxml)

4.index.js

// index.js

Component({

  properties: {},

  data: {},

  methods: {},

});

5. index.json

{

  "component": true,

  "renderer": "xr-frame",

  "usingComponents":{}

}

6. index.wxml(页面3d渲染内容，详情参考文档）

<xr-scene>

<xr-assets bind:progress="handleAssetsProgress" bind:loaded="handleAssetsLoaded">
 <xr-asset-load type="gltf" asset-id="damage-helmet" src="/static/gltf/lou.gltf" />

</xr-assets>

<xr-light type="ambient" color="1 1 1" intensity="1" />
<xr-light type="directional" rotation="40 70 0" color="1 1 1" intensity="3" cast-shadow />

<xr-gltf node-id="damage-helmet" model="damage-helmet" />
<xr-gltf model="miku" position="-0.15 0.75 0" scale="0.07 0.07 0.07" rotation="0 180 0" anim-autoplay />

<xr-camera
  position="0 15 60" target="damage-helmet" background="skybox"
  clear-color="0.4 0.8 0.6 1" camera-orbit-control
/>
</xr-scene>

7. 页面.vue

<template>
  <view style="display: flex; flex-direction: column">
    <xr-start
      id="main-frame"
      disable-scroll
      :width="renderWidth"
      :height="renderHeight"
      :style="'width:' + width + 'px;height:' + height + 'px;'"
    >
    </xr-start>
  </view>
</template>

<script>
export default {
  data() {
    return {
      width: 300,
      height: 300,
      renderWidth: 300,
      renderHeight: 300,
    };
  },
  onLoad(option) {
    this.width = uni.getWindowInfo().windowWidth;
    this.height = uni.getWindowInfo().windowHeight;
    const dpi = uni.getWindowInfo().pixelRatio;
    this.renderWidth = this.width * dpi;
    this.renderHeight = this.height * dpi;
  },
  mounted() {},

  methods: {},
};
</script>
