Tile-by-tile Construction with the 3D Process

Federation construction from 3D source content data is based on the 'tiled 3D content processing' setup.
(Refer to Tiled 3D Content Processing for details.)
Federation tile meshes are then built from an iSourceTiling object to describe the tiling being used, together with a set of ground pieces generated for this tiling.

The process of constructing each federation tile mesh is then essentially as follows:

• Figure out which source tile pieces are overlapped by the federation tile's represented region, by calling iMeshFederation::getNumberOfGroundTilesOverlapped(), and then iMeshFederation::getGroundTilesOverlapped().
• Load these source tile pieces into memory.
• Compile a buffer with pointers to these source tile pieces.
• Pass this buffer into iMeshFederation::buildTileMeshFromLocalGroundTiles() to then go ahead and build the federation tile mesh.

Example code

The 'meshfederation' example project includes a code path for construction from 3D content processing tiled ground result pieces, but you need to comment in the relevant call in the example source code to see this in action.
Refer to the project documentation for more details.
