DrftSplats

A capture, as the writer is handed it.

interface DrftSplats

import type { DrftSplats } from '@driftengine/drft';

In depth

positions is read and never stored, which is the one surprising field here. The writer needs them to decide the coarse-first block layout, and the reader gets them back out of the records — so writing them a second time would be twelve bytes a splat of duplicate in the one place this format is trying hardest to be small.

Properties

Name	Type	Description
`count`readonly	`number`
`positions`readonly	`Float32Array`	Three per splat, in the capture's own space. Read for layout only.
`records`readonly	`Uint32Array`	`wordsPerSplat` `u32`s per splat, in `count` order. Opaque here.
`wordsPerSplat`readonly	`number`
`boundsMin`readonly	`Float32Array`
`boundsMax`readonly	`Float32Array`
`sphericalHarmonics`readonlyoptional	`number`	Coefficients the source carried and the packer did not read. Carried as a number.
`blocks`readonlyoptional	`number`	How many blocks to split the capture into, or absent for a size this writer chooses. More More blocks means a capture that opens sooner and a longer chunk table; each entry is sixteen bytes, so even thirty-two blocks is half a kilobyte against megabytes of records.
