In this chapter, we take a little step back from interaction and propose a system with simple interactions that however, addresses most of the open problems mentioned in Section~\ref{i:challenges}.
We take inspiration from video streaming: working on the similarities between video streaming and 3D streaming (seen in~\ref{i:video-vs-3d}), we benefit from the DASH efficiency (seen in~\ref{sote:dash}) for streaming 3D content.
DASH is based on content preparation and structuring which helps not only the streaming policies but also leads to a scalable and efficient system since it moves completely the load from the server to the clients.
A DASH client is simply a client that downloads the structure of the content, and then, depending on its needs independently of the server, decides what to download.
Section~\ref{d3:dash-3d} describes our content preparation and metadata, and all the preprocessing that is done to our model to allow efficient streaming.
