\section{Introduction}
|
|
|
|
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 downloads the structure of the content, and then, depending on its needs independently of the server, decides what to download.
|
|
|
|
In this chapter, we show how to mimic DASH video with 3D streaming, and we develop a system that keeps DASH benefits.
|
|
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.
|
|
Section~\ref{d3:dash-client} gives possible implementations of clients that exploit the content structure.
|
|
Section~\ref{d3:evaluation} evaluates the impact of the different parameters that appear both in the content preparation and the client.
|
|
Finally, Section~\ref{d3:conclusion} sums up our work and explains how it tackles the challenges raised in the conclusion of the previous chapter.
