Scene State Format

The scene-state format specifies the set of 3D model assets used in the scene together with their transforms.
There can be a arch field that specifies the architecture. The architecture can either be a reference to another json file or directly embedded.
To specify the arch by reference, use the ref field to specify the architecture id:
"arch": { "ref": "arch.00001" }
The transform is a 4x4 matrix in column order. In newer versions of the format, the scene-state can also include the rotation, translation and scale as vectors. The rotation vector is a quaternion in [x,y,z,w] order.
The model ids specify the asset source together with the asset id.
Example of scene-state file:
