?cv=1&cam=lon,lat,h,range,bearing,pitch

The orbit target (longitude and latitude to 6 decimals), its true height in meters (the scene height divided by the exaggeration), the eye distance in rendered meters, and the look direction: bearing in degrees clockwise from north, pitch in degrees from straight down. Scenes without an origin write cf=local with east and north meters in place of longitude and latitude. Links without cv are read as six scene-unit numbers (eye, then target) for older pages. The link is rewritten (with history.replaceState) on the first still frame after the camera moves. Other URL parameters and the hash are preserved; pages add their own through the link.app hook.

The codec is encodeCam and decodeCam in the core module, and a controller reads and writes links with readLink, applyLink and writeLink.
