Classes

SplatCapture: A capture assembled from blocks, one .drft chunk at a time.
SplatSorter: Hold the newest order, ask for a new one when the view has changed enough, and never queue.

DecodedImage: One decoded image: 8-bit RGBA, row-major from the top left, four bytes a texel.
SogMeta: What a .sog manifest declares. Field names are the file's, not this engine's.
SplatAppend: Where a block landed, so a caller uploads what arrived rather than the whole texture.
SplatCaptureOptions
SplatData: A capture packed for the GPU, plus the two things the CPU still needs.
SplatPass
SplatSorterOptions
SplatSortRequest: One sort, as the worker protocol and as the function's own parameter list.
SplatSortResult: What a sort answers with: the filled buffer, and how many entries of it are real.
SplatSortScratch: The arrays a sort reuses, allocated once by the caller.
SplatSource: A capture as a reader hands it over: linear values, one array per attribute.
SplatView: What a consumer hands the pass each frame.
SplatViewLocal: The camera as the sorter needs it: in the capture's coordinates rather than the world's.

browserWebpDecoder: The ordinary decoder: @driftengine/core's exact texel read.
createDefaultSplatSort: The shipped capability: a worker over the same sort this module runs on the main thread.
createSplatPass: Build a pass for one capture.
createSplatSortScratch
createSplatViewLocal
defaultSplatBudget: The budget to hand SplatSorter when the consumer has no number of its own.
packSplats: Turn a source into two texels per splat, and compute the capture's bounds while the loop is open.
readSogMeta: Parse and check a meta.json. Refuses a version it does not understand rather than guessing.
readSogSource: The same read, stopping one step short: the linear values, before they are packed for the GPU.
readSplat: Read a .splat capture.
readSplatPly: Read a .ply Gaussian capture.
readSplatSog: Read a .sog capture into a SplatSource.
resolveSplatView: Fill out with the camera, in the space the capture's own positions are written in.
sortOnMainThread
sortSplatsByDepth: Order the splats worth drawing far to near, writing indices into request.out.
splatBoundsVisible: Is any part of the box [boundsMin, boundsMax] inside the frustum?
splatsFromRecords: A whole capture in one go, for a caller that read the file rather than streamed it.
unbundleSog: Unpack a bundled .sog, which is a ZIP with every file at the root.

SogFiles: The files a capture is made of, by the names its manifest gives them.
SplatSortFn: How a sort actually happens.
WebpDecoder: What turns a WebP file's bytes into texels. See this file's header for why it is a parameter.

SOG_VERSION: The container version this reader understands.
SPLAT_BUDGET_DEFAULT: The count a part this engine has no evidence against is asked to draw.
SPLAT_BUDGET_WEAK: The count a part measured to struggle with the good profile is asked to draw.
SPLAT_RECORD_BYTES: Position, scale, colour and rotation, in that order, little-endian.
SPLAT_SH1_COEFFICIENTS: Three basis functions at l=1, three channels each.
SPLAT_SIZE_BUCKETS: How many buckets the screen-space size key has.
SPLAT_SORT_BUCKETS: How many buckets the depth key has. A sixteen-bit key, so 65,536 of them.
SPLAT_STRIDE: Splats per row.
SPLAT_WORDS: How many uint32s a splat occupies with no view-dependent colour: two RGBA32UI texels.
SPLAT_WORDS_SH1: The same with degree-1 view-dependent colour: one more texel, and no more than one.
