Close up no longer falls apart: how near the nearest thing is goes by each object's box (not a ball round it: inside a big or long flat one's ball it came to nothing, the near plane with it, and surfaces fought each other in blocks, jittering, the sky and grid gone), the near plane a quarter of the way to it; reference pictures count too. Grid lines meet exactly where their pieces join (no crawling dots): a streak's ends each face the eye, each its own width; pieces a quarter further from the eye each. The depth pre-pass waited on before the scene uses it; the same depth in both (invariant)
