Translate along world axis after rotation in Three.js

Question

I'm just beginning to learn Three.js and 3D programming in general. I have a camera that is rotated 45 degrees 'down' around x-axis. When I translate after rotating, the camera only moves along its local axes. How can I get it to move along the world x and z axes?

Answer 1

camera.position.x += delta;
camera.position.z += delta;
