 Clicking on a bookmark to fly to another viewpoint leads to reduced data locality.
 The 3D content at the  bookmarked destination viewpoint may overlap less with the current viewpoint.
 In the worst case, the 3D objects corresponding to the current and destination viewpoints can be completely disjoint.

 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 #link("https://sketchfab.com")[sketchfab.com], #link("https://cl3ver.com")[cl3ver.com] among others) and in academia, as reported below.

 In the case of streaming a large 3D scene, view-dependent streaming is fundamental: 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 induce a low quality of experience.
