 \section{3D Bookmarks and Navigation Aids}
 
 Devising an ergonomic technique for browsing 3D environments through a 2D interface is difficult.
-Controlling the viewpoint in 3D (6 DOFs) with 2D devices is not only inherently challenging but also strongly task-dependent. In their recent review,~\citep{interaction-3d-environment} distinguish between several types of camera movements: general movements for exploration (e.g., navigation with no explicit target), targeted movements (e.g., searching and/or examining a model in detail), specified trajectory (e.g., a cinematographic camera path), etc.

 For each type of movement, specialized 3D interaction techniques can be designed.
 In most cases, rotating, panning, and zooming movements are required, and users are consequently forced to switch back and forth among several navigation modes, leading to interactions that are too complicated overall for a layperson.
 Navigation aids and smart widgets are required and subject to research efforts both in 3D companies (see \url{sketchfab.com}, \url{cl3ver.com} among others) and in academia, as reported below.

 A simple approach is to retrieve the objects based on distance: the spatial distance from the user's virtual location and rotational distance from the user's view.

 Even though there are no associated publications, it seems that the interface does view dependent streaming: low resolution from the center of the point of view gets downloaded right away, and then, data farther away or higher resolution data gets downloaded.
 
 In the same vein, \citep{3d-tiles} developed 3D Tiles, is a specification for visualizing massive 3D geospatial data developed by Cesium and built on top of glTF\@.

 A client typically starts by downloading the MPD file, and then proceeds on downloading segments of the different adaptation sets that he needs, estimating itself its downloading speed and choosing itself whether it needs to change representation or not.

+DASH has already been adopted in the setting of video streaming.
 DASH-SRD (Spatial Relationship Description,~\citep{dash-srd}) is a feature that extends the DASH standard to allow streaming only a spatial subpart of a video to a device.
 It works by encoding a video at multiple resolutions, and tiling the highest resolutions as shown in Figure~\ref{sota:srd-png}.
 That way, a client can choose to download either the low resolution of the whole video or higher resolutions of a subpart of the video.
