solved Why this -Z camera up vector is not working?

[kkimdev]

Hi I'm trying to set -Z as the camera up vector but it doesn't render properly like the following.

Setting the up vector to (1,0,0) or (0,1,0) works though.

Thanks. I tried your example, but when I control the camera by mouse dragging it breaks badly.  Do you know the reason?

[Nabroski]

No, sorry, i must pass here. I understand where the problem is, but for a quick fix, i would like ping @Deltakosh

The reason: mouseEvents are { scoped functions } and listening in a loop on changes, when you click with the mouse the default cached -state of the Babylonjs Camera is activated. So the fix would be to implement own mouseHandlers and rotate the Camera from their.

Just wait for Deltak. he can explain it better i guess.

Hello this is because the default camera handlers expect the up vector to be 0,1,0.

 

As @Nabroski mentioned, the best idea would be to implement your own input: http://doc.babylonjs.com/how_to/customizing_camera_inputs

This is the default one for the record: https://github.com/BabylonJS/Babylon.js/blob/master/src/Cameras/Inputs/babylon.freeCameraMouseInput.ts
