Question

I'm trying to animate this vase so it just rotates in place around its y axis, but it's doing that while moving in a circle, leading me to believe that I need to move the anchor's position (wish I knew how). You can see the VR scene here. Here's my code for this rotating asset:

<a-entity position=".7 1 -3">
          <a-gltf-model id="testvase1" rotation = "0 0 0" scale=".05 .05 .05"
                       src="#gltf" position="-.08 0 -.005">
          </a-gltf-model>
           <a-animation attribute="rotation" dur="10000" 
                       from= "0 0 0" to="0 360 0" repeat="indefinite"></a-animation>    
        </a-entity>

两个问题：

不要平移对象使其绕中心旋转。

<a-entity position="0 0 0">
  <a-gltf-model id="testvase1" rotation = "0 0 0" scale="2 2 2" src="#gltf" position="0 0 0"></a-gltf-model>
  <a-animation attribute="rotation" dur="10000" from= "0 0 0" to="0 360 0" repeat="indefinite"></a-animation>    
</a-entity>

您的模型不在坐标原点的中心。您将需要导入3d包（例如Blender）并重新导出为中心。这是一个示例，其中包含您的代码和一个居中的模型：https://glitch.com/edit/#!/utopian-walleye?path=public/index.html:32:19
