Can the ArcCamera be set to trackball mode?
The effect is similar to three.js’s TrackballControls . (three.js examples)

Hello and welcome

A trackball solution had been given in this topic :

Blender "trackball" orbit method for arcRotateCamera

Hi Is it possible to have the same comportment as “trackball” orbit method in Blender with an arc rotate camera ? The default comportment is more like the “turntable” one, wich always make a world UP axis rotation, where the “trackball” seems to rotate around the transformed UP axis of the camera I tried to change updateUpVectorFromRotation but doesn’t seems to be that Thank you !!

How to adjust TransformNode when the camera pans and zooms?

@Tricotou This solution is definitely wrong. You can set the camera’s beta to 0 and alpha to Math.PI / 2, and run the code again. It is basically wrong.

The demo playground seems to work for me.
