Crate spatialrust_interchange 

glTF, OpenUSD, and OGC 3D Tiles scene interchange adapters.

openusd provides in-memory stages plus USDA ASCII mesh export/import. tiles3d provides deterministic OGC 3D Tiles 1.1 point-cloud tilesets (tileset.json + pnts payloads). Native libusd bindings remain optional and outside the default tree.

Structs

BuiltTile

One generated tile payload paired with its content URI.

BuiltTileset

A validated tileset plus its pnts payloads.

CopcTilesetOptions

Options controlling COPC → 3D Tiles export.

MemoryUsdStageAdapter

In-memory USD stage adapter (no OpenUSD native dependency).

PntsFeatureTable

Feature-table data carried by one pnts tile.

Tile

One tile in a 3D Tiles hierarchy.

TileContent

Content reference for a tile.

Tileset

Root document of a 3D Tiles tileset.

TilesetBuilderOptions

Options controlling octree construction.

TilesetWriteReceipt

Receipt for a written 3D Tiles tileset.

UsdPrimPath

Hierarchical USD prim path.

UsdStageDescription

Host-side USD stage description used before optional bindings land.

Enums

BoundingVolume

Bounding volume for a tile.

InterchangeError

Failures converting scenes to/from interchange formats.

Refinement

Supported refinement policy for a tile.

Traits

UsdStageAdapter

Adapter interface for composing / exporting OpenUSD stages.

Functions

build_point_tileset

Builds a deterministic octree tileset from interleaved positions.

decode_pnts

Decodes a complete pnts tile into its feature table.

decode_triangle_mesh_gltf_json

Decodes a SpatialRust-exported glTF JSON mesh with embedded base64 buffers.

encode_pnts

Encodes a feature table into a complete pnts tile (header + JSON + binary).

export_copc_tileset

Exports a COPC file into a 3D Tiles 1.1 tileset without materializing the whole cloud. Returns the byte/point/tile receipt.

export_stage_usda

Exports all meshes from a memory stage as a single USDA ASCII document.

export_triangle_mesh_gltf_json

Exports a triangle mesh to a minimal glTF 2.0 JSON document (embedded base64 positions/indices).

import_mesh_from_usda

Imports the first SpatialRust-authored Mesh prim from USDA ASCII.

import_triangle_mesh_gltf_json

Imports vertex/index counts from a SpatialRust-exported glTF JSON fragment.

parse_tileset_json

Parses and validates a 3D Tiles 1.1 tileset.json string.

serialize_tileset_json

Serializes a tileset to a 3D Tiles 1.1 tileset.json string.

write_point_tileset

Writes a built tileset to dir as tileset.json plus one .pnts file per tile.

Type Aliases

InterchangeResult

Result type for interchange adapters.
