pub const TRACE_DENSITY: f32 = 0.08;Expand description
At or below this density, the drawn count is a fraction of the tier’s
anchor — the same number of trajectories at every render target
(ADR-0195).
The boundary brackets the gap the authored population leaves: the densest
trace world in presets/ sits at 0.06 and the sparsest figure at 0.18,
so both ends of the band TRACE_DENSITY..=CLOUD_DENSITY fall in empty
space. A density inside the band is legal and scales partly with the target.
