ArcRotateCamera around axes other than world X and Y


Recommended Posts


ArcRotateCamera is a really greate camera.
I'm wondering if it can be made around some other axes instead of world X and Y. Because I mainly work in a Z-up coordinate system, and sometimes, I need to align the viewport to an arbitrary rectangle in 3D and do some panning.

Using a parent for the camera can make rotation work but seems not panning:

What I did was hacking the rebuildAnglesAndRadius and _getViewMatrix methods code, changing the computation of alpha, beta and target. This works for me but is too hacky.

What's your suggestion?
It's appreciated if there's a convenient way.


Thanks @Deltakosh for responding here https://github.com/BabylonJS/Babylon.js/issues/3392#issuecomment-351732710 .

Yes I did try to set the upVector to `new BABYLON.Vector3(0, 0, 1);` but it did not work.


To what value should I set upVector?


Thank you very much!
