three.js - Gimbal lock at y axis 90 degrees -


i found problem rotations. using transform controls helper, if rotate mesh on y axis, when reach 90 degrees flipped -180 degrees.

i think due software avoiding gimbal lock, how avoid it? that is, x- , z-angles remain 0 degrees in display.

i tried on threejs editor (https://threejs.org/editor/) , occurs there. please me :)!

what describing has nothing gimbal lock.

three.js quaternion-based. equivalent euler angle representation provided convenience.

euler angles not unique; there many euler angles represent same orientation. see this answer info on how euler angles work in three.js.

if want rotate object on y-axis only, , have object.rotation.y continuous, can changing rotation order so:

object.rotation.order = 'yxz';

three.js r.87

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
