 In order to be able to evaluate our system, we need to collect traces and perform analyses on them.
-Since our scene is large, and since the system we are describing allows navigating in a streaming scene, we developed a web client that implements our utility metrics and policies.

+Performance of our system is a key aspect in our work; as such, we can not use the default geometries described in Section~\ref{f:geometries} because of its poor performance, and we instead use buffer geometries.
 However, in our system, the way changes happen to the 3D content is always the same: we only add faces and textures to the model.

 \paragraph{Our 3D model class.\label{d3:model-class}}
 As said in the previous subsections, a geometry and a material are bound together in a mesh.
 This means that we are forced to have as many meshes as there are materials in our model.
-To make this easy to manage, we make a \textbf{Model} class, that holds both geometry and textures.

 In JavaScript, there is no way of doing parallel computing without using \emph{web workers}.
 A web worker is a script in JavaScript that runs in the background, on a separate thread and that can communicate with the main script by sending and receiving messages.
-Since our system has many tasks to do, it seems natural to use workers to manage the streaming without impacting the framerate of the renderer.
+Since our system has many tasks to perform, it is natural to use workers to manage the streaming without impacting the framerate of the renderer.
 However, what a worker can do is very limited, since it cannot access the variables of the main script.
-Because of this, we are forced to run the renderer on the main script, where it can access the HTML page, and we move all the other tasks to the worker (the access client, the control engine and the segment parsers).
+Because of this, we are forced to run the renderer on the main script, where it can access the HTML page, and we move all the other tasks (i.e. the access client, the control engine and the segment parsers) to the worker.
 Since the main script is the only thread communicating with the GPU, it will still have to update the model with the parsed content it receives from the worker.
 Using a worker does not so much improve the framerate of the system, but it reduces the latency that occurs when receiving a new segment, which can be very frustrating since in a single thread scenario, each time a segment is received, the interface freezes for around half a second.
 A sequence diagram of what happens when downloading, parsing and rendering content is shown in Figure~\ref{d3:sequence}.
