cesium glft 大量

Cesium的glTF功能可以通过使用Cesium的gltf模型加载器来实现。您可以使用以下代码将大量的glTF模型加载到Cesium中：

function loadGltfModels(modelUrls) {
  var modelPromises = [];
  for (var i = 0; i < modelUrls.length; i++) {
    var modelUrl = modelUrls[i];
    var promise = Cesium.Model.fromGltf({
      url: modelUrl,
      scale: 1.0
    });
    modelPromises.push(promise);
  }

  Cesium.when.all(modelPromises, function(models) {
    for (var i = 0; i < models.length; i++) {
      var model = models[i];
      scene.primitives.add(model);
    }
  });
}

var modelUrls = ["model1.gltf", "model2.gltf", "model3.gltf"];
loadGltfModels(modelUrls);
