3d camera center in data coordinates

Hi.

Same issue that the #5524 : https://github.com/plotly/plotly.js/issues/5524

It is impossible to fix the rotation point to a specific point to analyse data around this point.

Example : https://codepen.io/someuser12/pen/rNXLPRJ

The center is located at 0,0,0 in the layout (center of one of the sphere) but the rotation point is located at the middle of the graph at 500,0,0 (why ?)

If i change the center with the different button (for exemple fix it at x = 1000), the plot disappear to infinity and beyond.

Would be nice to have this feature to be able to navigate around a 3d system and analyse what happened.

In my case, we study (and plot) birds trajectories around wind turbine. We need to rotate around a specific point of the bird trajectory.

Regards

まず issue #5524 とリンク先の CodePen の例を確認し、3D カメラの動作を再現します。再現結果を起点に既存の 3D カメラ実装を追跡します。完了条件は、プロットが消えることなく、指定したデータ座標上の点を中心に回転できることです。
