There is a significant deviation in the camera position

Clicking on the same coordinate (alpha, beta, radius) causes the camera to stop at different positions

That will be very difficult to help without a repro in the Playground (I think “Clicking on the same coordinate (alpha, beta, radius)” is very specific to your project and we would need to see how it is done).

Unfortunately, I am unable to upload the model to the public network, so it cannot be displayed in PG. After my testing, when the model is relatively large, setting the same coordinate will return positions with significant differences, perhaps due to insufficient accuracy. My current approach is to set the size of the model to 10 through scaling. Although there is still a loss of accuracy, it can already be basically run
