SogBundle¶

from acron.sog import SogBundle

class SogBundle(native: GSplatBundle)¶

Bases: object

A splat bundle: the native GSplatBundle (native) and its planes as memoryviews. Built by the readers and the encoders, not by hand.

property codebook: SplatArray¶

scales, sh0, shN codebooks, 0 — the LUT the shader samples (a read-only view of the native codebook).

Type:: (256, 4) float32

property means_bounds: tuple[LVecBase3f, LVecBase3f]¶

property meta: dict¶: The bundle’s meta.json (the file’s own for a read .sog).

property name: str¶

property planes: dict¶: name -> (H, W, 4) uint8 memoryview in image order (row 0 = top), over the native plane (no copy; read-only).

property sh_coeffs_per_channel: int¶: Coefficients per colour channel the bundle’s palette holds (3 / 8 / 15 for 1 / 2 / 3 bands), from the centroid image’s width.

sh_entries_per_row¶: Palette entries per centroid-image row (64 in a .sog; wider for a direct palette).

property sh_planes: dict¶: shN_labels / shN_centroids as planes, when read with SH.
