The OGC 3D Tiles protocol is designed for streaming and rendering massive 3D geospatial content such as Photogrammetry, 3D Buildings, BIM/CAD, Instanced Features, and Point Clouds from a server to a client. It defines a hierarchical data structure and a set of tile formats which deliver renderable content.
LuciadRIA supports OGC 3D Tiles of version 1.0 and 1.1. They can contain a payload with:
PNTS
format)
B3DM
or Batched 3D Model format.
GLB
or Binary Graphics Library Transmission format
glTF
or Graphics Library Transmission format
The OGC 3D Tiles format describes the structure of a 3D tile hierarchy. It consists of:
tileset.json
.
It can link to other tileset.json
files or data files.
It can also describe the 3D scene implicitly, if the scene is subdivided using
a perfect (sparse) quadtree or octree. In that case, it contains much less information
in itself. It will link to {level}_{x}_{y}_{z}.subtree
files
for information about tile and content existence at a certain level. In the case of implicit tiling,
the information about the bounding volume and the geometric error can be deduced automatically.
