Question

我试图通过aframe平台播放360视频时观察观看者的方向。输出可以是FOV的中点值（视野）...有谁知道怎么做？请帮帮我!!

如果您从A-Frame主页开始使用全景示例，您可以像这样更改它以获得角度：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Panorama</title>
    <meta name="description" content="Panorama — A-Frame">
    <script src='//cdnjs.cloudflare.com/ajax/libs/aframe/0.5.0/aframe.js'></script>

    <script>
      AFRAME.registerComponent('theta', {
          tick: function (time, timeDelta) {
            var camera = this.el.object3D.children[0]
            vector = camera.getWorldDirection();
            theta = Math.atan2(vector.x,vector.z);
            console.log(theta);
          },
      });
    </script>

  </head>
  <body>
    <a-scene>
      <a-camera theta></a-camera>
      <a-sky src="puydesancy.jpg" rotation="0 -130 0"></a-sky>
    </a-scene>
  </body>
</html>

（通过Three.js: Get the Direction in which the Camera is Looking）

随时查看观看者的观看方向
