Spherical Coordinates for Gamers
{"Image DocumentName": "Spherical Coordinates for Gamers", "Image ImageDescription": "The horizontal angle \u03b8 we will rename to h, which is short for heading and is similar to a compass heading. A heading of zero indicates a direction of forward or to the north , depending on the context. This matches the standard aviation conventions. If we assume our 3D cartesian conventions described in Chapter 1, then a heading of zero (and thus our primary polar axis) corresponds to +z. Also, since we prefer a left-handed coordinate system, positive rotation will rotate clockwise when viewed from above.
