Follow camera

The follow camera stands behind the character today: it orbits a pivot at a share of the body's height, is pulled in by the ground, the water and the landmarks, and in photo mode orbits the held body. Its pitch limits and the wheel's nearest and furthest distances are the game's own, read from the game's camera profile; its field of view is the game's too, the 45 degrees the game sets its world camera to at run time, as a published field-of-view tool reads it, since the profile holds none; and its pivot is read off recordings. How far a notch moves the eye, how fast it eases back out and how far a reset tilts it are still provisional, and the settings the game offers for the camera are not there yet.

Decisions

• What the camera profile cannot say is read off one recording. The profile holds the zoom's input ratio and the radius's lerp-back ratios, but the Zoom module eases a velocity and what the game computes from each ratio lives in code no dump holds. So the wheel's step and the eye's return are measured on follow-camera.mkv, the clip the roadmap owes, as the eye's distance over time. Its reset before a flat horizon tells whether the game levels the camera or tilts it down by the default elevation the profile's first words hold, and its tilt from level to straight down whether the arm lengthens as the profile's radius added at the steepest elevation says.
• The game's settings for this camera. Its horizontal and vertical sensitivity, its default distance between 4.5 and 6.0, which the camera returns to after a zoom, after combat and after a teleport, and whether its pitch follows the slope as the character climbs or descends, are read from the menu screens' Settings, each with the game's range and default. The default distance is metres of the arm: its span is the profile's setting adjustment and its top the profile's furthest radius on foot.
• A sensitivity turns the look in proportion to it. The wiki gives each sensitivity's range, 1 to 5, and no curve, so the look's radians a pixel are scaled by the setting over the middle of that range, 3, which turns the camera as it turns today.
• Photo mode's range is the game's, solved off recordings. Photo mode moves its camera round the character by the game's two sliders, one horizontal and one vertical, and its zoom, within the game's range. Until a recording solves that range, photo mode shares the follow camera's range, a provisional call the as-built page records.

Scope and order

Today: the field of view, the pitch limits and the wheel's range are the game's, and the pivot is measured; a notch's zoom and the ease back out are provisional, the reset levels the camera, its sensitivity and default distance are read from the settings at the game's defaults, which the Settings screen does not set yet, and photo mode orbits the held character within the follow camera's range, not the game's.

This adds, in order:

1. The recording. follow-camera.mkv on the roadmap's Recordings owed list, each of the four readings above kept in the character's reference and written over its provisional constant. Photo mode's sliders and zoom at their ends, photo-mode-range.mkv, solve its range.
2. The settings' rows on the Settings screen, and the slope's pitch, once the menu screens build its Controls tab. The defaults the camera starts at are read off that tab's export, which replaces FOLLOW_CAMERA_DEFAULT_SETTINGS' provisional values.

The camera is approved by its own measure: at each reading of the recording, the eye's distance and its ease match the camera's within the reading's noise.

What this does not propose

• The cameras of combat: the automatic pans its setting turns on, the aimed shot's camera, the shake of a hit and the pull the profile's combat fields hold. Each comes with combat.
• The boat's camera and the cameras of cutscenes, which come with what they film.
• Photo mode's own screen: its blur, the character's expressions and poses, and its shutter. Photo mode here is the camera alone.
