 \subsection{Viewpoint dependency}
 
+3D streaming means that content is downloaded while the user is interacting with the 3D object.
+In terms of quality of experience, it is desirable that the downloaded content is visible to the user.
+This means that the progressive compression must allow a decoder to choose what it needs to decode, and to guess what it needs to decode from the users point of view.
+This is typically called \emph{random accessible mesh compression}.
+\citep{maglo2013pomar} is such an example of random accessible progressive mesh compression.
+
 In the case of large scene 3D streaming, viewpoint dependent streaming is a must-have: a user will only be seeing one small portion of the scene at each time, and a system that does not adapt its streaming to the user's point of view is bound to have poor quality of experience.
 
 A simple way to implement viewpoint dependency is to access the content near the user's camera.

+\citep{simon2019streaming} propose a way to stream a set of textures by encoding the textures into a video.
+Each texture is segmented into tiles of a fixed size.
+Those tiles are then ordered to minimise dissimilarities between consecutive tiles, and encoded as a video.
+By benefiting from the video compression techniques, they are able to reach a better rate-distortion ratio than webp, which is the new standard for texture transmission, and jpeg.
