Member Function Documentation

extractGltfFromB3dm()

QgsCesiumUtils::B3DMContents QgsCesiumUtils::extractGltfFromB3dm ( const QByteArray & tileContent )

static

Extracts GLTF binary data and other contents from the legacy b3dm (Batched 3D Model) tile format.

Returns empty byte array on error.

Definition at line 144 of file qgscesiumutils.cpp.

extractGltfFromTileContent()

QgsCesiumUtils::TileContents QgsCesiumUtils::extractGltfFromTileContent ( const QByteArray & tileContent )

static

Parses tile content.

Returns empty byte array on error.

Note

cmpt, pnts, i3dm tile types are currently not supported

Deprecated

QGIS 4.2. : use extractTileContent() which can handle composite tiles as well.

Definition at line 258 of file qgscesiumutils.cpp.

extractTileContent()

QVector< QgsCesiumUtils::TileContents > QgsCesiumUtils::extractTileContent ( const QByteArray & tileContent )

static

Parses tile content and returns a list of TileContents.

For b3dm and glTF tiles, the returned list will contain a single entry. For cmpt (composite) tiles, the returned list will contain one entry per inner tile that could be successfully parsed. Returns an empty list on error or for unsupported tile types (pnts, i3dm).
