Unless you'd like to ask how to determine the facing direction from Euler angles or quaternions. (Hint: Euler angles are just the two angles you're already using, plus an extra one for rolling the camera about its view axis) | |
| Jun 26, 2018 at 13:02 | comment | added | user1095108 | I can delete my question, if you want. I just find it hard to know, where the camera is pointed at, if it is specified with a quat, or even 3 euler angles, while with unit sphere angles I know immediately where the camera is pointed at. | |

If you haven't found a need for them in your camera logic yet, then it's probably because you don't need them for what you're doing. Camera control is one case where we often want bias & poles (eg in a typical FPS camera where we can yaw 360° but only pitch ±90° or less) | |

| Jun 26, 2018 at 12:21 | comment | added | DMGregory♦ | Don't ask for permission, just do it and ask for help if it goes wrong. ;) Even if no developer on Earth had done this before, if it works for your case, that's all you need. But yes, storing a camera orientation as angles and building a matrix from that is a common approach. Have you encountered any trouble putting this into practice? | |
