Overview

The unit circle of yaw on the XZ-plane has 0° at (0, 1), 90° at (-1, 0), 180° at (0, -1) and 270° at (1, 0).

Yaw is not clamped to between 0° and 360°; any number is valid, including negative numbers and numbers greater than 360°.

Pitch 0 is looking straight ahead, -90° is looking straight up, and 90° is looking straight down.

There are an infinite number of "down"/"up" looks with different yaw; use e.g. NORTH.down.
