Cesium 视频纹理

话不多说，直接上代码

  <video id="video_dom">
    <source src="./video.mp4" type="video/mp4" />
  </video>
      var videoElement = document.getElementById("video_dom");
      videoElement.play();
      viewer.entities.add({
        polygon: {
          hierarchy: Cesium.Cartesian3.fromDegreesArray(lnglat),
          material: videoElement,
        },
      });
