Interface: LineLayout

Experimental

Result of buildLineLayout.

Properties

Property	Type	Description
head	number	Experimental First stream vertex (0 unless built with an offset). Streaming (E7.2) slides the live range inside the arrays instead of moving data, so GPU uploads stay proportional to the change.
instanceCount	number	Experimental Number of segment instances to draw (max(0, vertexCount - 3)).
origin	Vec3	Experimental Float64 RTC origin subtracted from positions.
points	Float32Array	Experimental Stream positions: [x - ox, y - oy, z - oz, valid] per vertex, valid for [head, head + vertexCount). Length ≥ 4 * (head + vertexCount).
source	Int32Array	Experimental Source serial of each stream vertex, or -1 for a sentinel: the input index plus sourceBase. Valid for [head, head + vertexCount); the length is the capacity.
sourceBase	number	Experimental Added to input indices to form source serials (0 for a plain build). Streaming edits renumber the inputs without rewriting retained vertices by changing the base instead.
vertexCount	number	Experimental Number of stream vertices, including sentinels.
