Object 3D Default up rotates edge selectors

[sam-thomas-dd]

Hi! Thanks for the great library.

Just wanted to report that setting

THREE.Object3D.DEFAULT_UP = new THREE.Vector3(0, 0, 1);

Results in some of the edge selectors being incorrectly oriented

Thanks for pointing that out! I must ask, after setting the default up, is that the only side effect you're facing, is everything else working as expected?

[sam-thomas-dd]

I think the orientation may also be incorrect. Front is where I expect top to be but that could be a preference.

Absolutely agree, it's a fantastic library!

The orientation is incorrect, but I was sort of able to fix this by changing the labels. When I click on Top though, the faces to the north and south are not Front and Back, but Right and Left.

Another much bigger issue is that clicking and dragging on the cube with Z-Up orientation is completely wonky and rotates quite unpredictably. Up and down mouse movement rotates the camera around the Z axis by a total of 180 degrees, and right and left rotates weirdly on both x and y axes simultaneously

I am having the exact same problem as Sean, although I only do camera.up.set(0, 0, 1) to set the z-axis as up.

I can confirm what Sean and Johan are saying. The function for rotating the camera when dragging the gizmo seems to only work with Y-axis up, any other axis up produces weird results. Clicking to rotate still works, at least in the default gizmo.

Hi! Thanks for your support and for reporting this issue.

The issue with the edge selectors has been fixed—they should now be correctly oriented. However, the gizmo still doesn’t fully handle Z-up (or any custom up direction different from the default) properly.

If anyone wants to contribute, your help is more than welcome! 🚀

Best,
