I passed the following method to adjust point cloud height not work:  
const cartographic = S3DP.Cartographic.fromCartesian(tileset.boundingSphere.center);  
const surface = S3DP.Cartesian3.fromRadians(cartographic.longitude, cartographic.latitude, 0.0);  
const offset = S3DP.Cartesian3.fromRadians(cartographic.longitude, cartographic.latitude, \_3dTilesLayer.height);  
const translation = S3DP.Cartesian3.subtract(offset, surface, new S3DP.Cartesian3());  
tileset.modelMatrix = S3DP.Matrix4.fromTranslation(translation);  
other method to adjust point cloud height?

@zyy1987 your code looks correct, and I tested in [this Sandcastle](https://sandcastle.cesium.com/#c=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). If you change the value of the height in `offset` the tileset’s height goes up and down as expected.

Could it be something with the `_3dTilesLayer.height ` you’re passing in?

Thank you for your reply。
