Open SC-19 intercept of FY-1C in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.
These are the sourced elements. This page does not print a position: a position is a function of time, and a single one dated to the bake would be stale the moment it was read. The registry composes a position for any date, past or future, from these elements — open the scene below and set the clock.
