Building a free flying 3D Quaternion camera

Hi Everyone,

Ok… so i’ve been trying to build a free flying camera.
I’ve used quaternions to handle rotations with success.

Only one part of mechanics seems to be eluding me. movement.

how do i find out after the rotations have been applied what my new relative forward vector is, so that i can translate in the right direction…

Im sure there is likely a simple answer that im just missing.

thanks for any help
