 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.
+\citep{cheng2008receiver} proposes a receiver driven way of achieving viewpoint dependency with progressive mesh: the client starts by downloading the base mesh, and then is able to estimate the importance of vertex splits and choose which ones to download.
+Doing so reduces drastically the server computational load, since it only has to send data, and improves the scalability of this framework.
 
 In the case of streaming a large 3D scene, 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.
