coarseningreadonly
The multiple of cellPixels the selection is made at: 1 when the cap
never bound, a power of COARSEN_STEP when it did. Reported so a count
can be read beside the tolerance that produced it, and handed back as
the next walk's coarsening.
culledreadonly
Nodes dropped beyond the horizon. Most of a planet, most of the time.
deepestLevelreadonly
patchesreadonly
Everything to draw.
Deterministic — the same eye and body give the same array, which is the property that matters — but the order is the traversal's own and is not sorted by anything a caller would want. A streamer spending a per-frame budget on it has to order it itself.
saturatedreadonly
True when maxPatches stopped the refinement a level early at the
loosest tolerance — or when the balance pass, which never leaves a 2:1
violation unsplit, carried a saturated selection past the cap. The cap is
a safety net, not a bound: an unsplit violation is a lit crack, which is
strictly worse than a flagged overrun.
shallowestLevelreadonly
starvedreadonly
Nodes that stopped short because ready said a child was not there.
The regions rather than a count, because they are what a streamer has to do
something about: these are the patches being drawn coarse right now, and
their four children are the next thing worth a worker. Empty when no
ready was given, which is the question the request set asks.
visitedreadonly
Nodes the traversal looked at — what the selection cost.
