Question

我无法使用ar.js显示我的glb用于图像跟踪请检查我的网页https://ignaciostellino.github.io./ 我能够识别图像，但无法显示3D模型。我想应该与规模和位置有关，但无法弄清楚。这是我的代码：

<script src="https://cdn.jsdelivr.net/gh/aframevr/aframe@1c2407b26c61958baa93967b5412487cd94b290b/dist/aframe-master.min.js"></script>
<script src="https://raw.githack.com/AR-js-org/AR.js/master/aframe/build/aframe-ar-nft.js"></script>

<style>
  .arjs-loader {
    height: 100%;
    width: 100%;
    position: absolute;
    top: 0;
    left: 0;
    background-color: rgba(0, 0, 0, 0.8);
    z-index: 9999;
    display: flex;
    justify-content: center;
    align-items: center;
  }

  .arjs-loader div {
    text-align: center;
    font-size: 1.25em;
    color: white;
  }
</style>

<body style="margin : 0px; overflow: hidden;">
  <!-- minimal loader shown until image descriptors are loaded -->
  <div class="arjs-loader">
    <div>Loading, please wait...</div>
  </div>
  <a-scene
    vr-mode-ui="enabled: false;"
    renderer="logarithmicDepthBuffer: true;"
    embedded

  </a-scene>
</body>

我不确定问题出在哪里，也许您的模型太小或太大。您如何确定检测到标记？尝试使用<a-gltf-model>代替<a-entity>。您还可以使用我们的平台echoAR上传您的模型并立即获得AR.js体验链接（了解here的用法）。您可以将代码与自动生成的代码进行比较，也可以只使用获得的ARjs链接。

Ar.js无法显示glb模型
