Quaternion to Euler

[max123]

Hi,

Another head scratcher for me: I'm trying to cast rays to detect if an a object (A) is in "view" of another object (B).
B has got lookAt(A) attached to it, so this is how I'm constructing the ray:

var ray = new BABYLON.Ray(this.mesh.position, this.mesh.rotationQuaternion.toEulerAngles().normalize());

It's not working, so what am I doing wrong?

BTW, I tried a variation:

var ray = new BABYLON.Ray(this.mesh.position, this.mesh.rotationQuaternion.normalize().toEulerAngles());

but still no joy...

This should be useful:

You might know this already, but when you use Mesh.lookAt, it points the negative z access at the lookAt point.

This worked!! Thanks a lot.
