I am working in new 3d editor for printing systems based on the threeJs editor but there is a needed to change default coordinate system from y-up to z-up. By searching in communities found some snippet code to implement that: camera.up.set(0, 0, 1); and rotate grid 90 ْ : grid.rotateX(Math.PI / …

Can you perhaps work with eulerOrder, something like camera.eulerOrder = “XZY”; ?

That’s not worked. camera.eulerOrder = “XZY”; I think it isn’t camera property !

It is a property of the Object3d and as such for the camera, and had helped me resolving a camera rotation issue (deprecating, now apparently ‘object.rotation.order’) . But you’re right, it is only for applying rotations using Euler, it doesn’t really effect the coordinate system when setting positi…

@Babak , did you find any solution for the above issue ? If yes, Can you please share it here ?

Depends on what you need the rotated axes for - for 3D printing it should be as simple as rotating the entire scene 90 degrees around the X or Z axis before exporting the model for printing.

OK, i solve this problem, you must init camera before orbitcontrols.

[image] Problem about rotation in orbitControls and camera up property Questions Description: I encountered a problem with the rotation behavior of orbitControls. When instantiating orbitControls without setting the camera’s “up” property correctly, the rotation behaves …

Instead of trying to force threejs to be z-up… (Which is a nightmare since SOO many components assume Y-up, like orbitcontrols, environment maps, etc.) Just put all your Z-up world underneath a new Group() that rotates -PI*.5 on x. let zUpRoot = new THREE.Group(); zUpRoot.rotation.x = -Math.PI*.…
