Detailed Description

Raw per-instance data parsed from an i3dm feature table of a single tile.

This struct transports i3dm instance data from the binary parser through TileContents to resolveInstancing() - to handle 3D Tiles 1.0 spec.

In 3D Tiles 1.1 spec, instanced meshes are handled by EXT_mesh_gpu_instancing glTF extension, and this struct is not used at all, because instancing is parsed directly from glTF nodes inside resolveInstancing().

All positions are in i3dm tile space (Z-up), relative to RTC_CENTER.

Note: Not available in Python bindings.

Since: QGIS 4.2
