在1.118中测试可行，可直接在Sandcastle中运行：

const viewer = new Cesium.Viewer("cesiumContainer", {terrain: Cesium.Terrain.fromWorldTerrain(),
});// Disable the ("globe") rotation for left mouse drags
viewer.scene.screenSpaceCameraController.enableRotate = false;let tileset = viewer.scene.primitives.add(await Cesium.Cesium3DTileset.fromIonAssetId(40866)
);// Store the transform of the root node of the
// tileset as the "root transform", assign this
// as the initial model matrix, and set the
// transform of the root node to be the identity
const rootTransform = Cesium.Matrix4.clone(tileset.root.transform);
tileset.modelMatrix = Cesium.Matrix4.clone(rootTransform);
tileset.root.transform = Cesium.Matrix4.clone(Cesium.Matrix4.IDENTITY);
const fullRotationMatrix = Cesium.Matrix4.clone(Cesium.Matrix4.IDENTITY);let selectedTileset;
let initialMousePosition;
const enableTransformEditor = true;const handler = new Cesium.ScreenSpaceEventHandler(viewer.scene.canvas);handler.setInputAction(async (click) => {const pickedObject = viewer.scene.pick(click.position);if (enableTransformEditor && pickedObject && !pickedObject.id) {selectedTileset = pickedObject.primitive;initialMousePosition = Cesium.Cartesian2.clone(click.position);}
}, Cesium.ScreenSpaceEventType.LEFT_DOWN);handler.setInputAction((click) => {selectedTileset = null;initialMousePosition = null;
}, Cesium.ScreenSpaceEventType.LEFT_UP);handler.setInputAction((movement) => {if (selectedTileset && initialMousePosition) {const translation = new Cesium.Cartesian3();Cesium.Matrix4.getTranslation(selectedTileset.modelMatrix, translation);const dx = movement.endPosition.x - initialMousePosition.x;const yaw = Cesium.Math.toRadians(dx);// Compute the rotation matrix, and multiply it// to the "full rotation matrix"const rotation3 = Cesium.Matrix3.fromRotationZ(yaw);const rotationMatrix = Cesium.Matrix4.fromRotation(rotation3);Cesium.Matrix4.multiply(fullRotationMatrix,rotationMatrix,fullRotationMatrix);// Compute the new model matrix from the// root transform and the full rotation matrixconst newModelMatrix = Cesium.Matrix4.clone(Cesium.Matrix4.IDENTITY);Cesium.Matrix4.multiply(rootTransform, fullRotationMatrix, newModelMatrix);// Apply the new model matrixselectedTileset.modelMatrix = newModelMatrix;// Update initialMousePosition for the next movementinitialMousePosition = Cesium.Cartesian2.clone(movement.endPosition);}
}, Cesium.ScreenSpaceEventType.MOUSE_MOVE);viewer.zoomTo(tileset);
