Left handed scene, but need to manage right handed transformnode


I need to display right handed axis with AxesViewer
how can I proceed ?


I am totally not sure what your use case is :frowning:

You could either work fully in right Handed with scene.useRightHandedSystem = true for consistency

You can also call axisViewer.update and provide the axis you want

or recreate an axis viewer from this code as the feature to show right handed in left handed is rather edge case: Babylon.js/axesViewer.ts at master · sebavan/Babylon.js · GitHub

I used it :
myaxis.update(Vector3.Zero(), new Vector3(-1, 0, 0), new Vector3(0, 1, 0), new Vector3(0, 0, 1));
