“…5 stated being not familiar with interactive 3D software, 6 barely familiar, and 1 somewhat familiar. On average, they rated their skills with Five different interfaces tested in the first preliminary pilot study: (a) photo shown on a proxy plane in the field of view [26]; (b) photo shown on proxy plane with white lines going from the POI to each camera visualizations; (c) a fading version of (b); (d) thumbnail preview in the corner with a red line visualization [9]; (e) thumbnails shown when mousing over a camera visualization [8]. 3D software as 1.667 on a 7-point Likert scale, where 1 is Novice and 7 is Expert.…”

“…In this paper, we focus especially on emerging image-based reconstructed scenes, which may be sparsely and incompletely reconstructed, and therefore, sophisticated image-based rendering methods are not always directly applicable. Instead, we choose the simple approaches of using proxy planes and thumbnail images, both of which are simple, are applicable to emerging mixed-reality scenes, and have been used in previous related work [8,26] (see Section 3.3).…”

Virtually navigating through photos from a 3D image-based reconstruction has recently become very popular in many applications. In this paper, we consider a particular virtual travel maneuver that is important for this type of virtual navigation-orbiting to photos that can see a point-of-interest (POI). The main challenge with this particular type of orbiting is how to give appropriate feedback to the user regarding the existence and information of each photo in 3D while allowing the user to manipulate three degrees-of-freedom (DoF) for orbiting around the POI. We present a hybrid approach that combines features from two baselinesproxy plane and thumbnail approaches. Experimental results indicate that users rated our hybrid approach more favorably for several qualitative questionnaire statements, and that the hybrid approach is preferred over both baselines for outdoor scenes.

We demonstrate the use of DASH, a widely-deployed standard for streaming video content, for streaming 3D content in an NVE (Networked Virtual Environment) consisting of 3D geometry and associated textures. We have developed a DASH client for NVE to show how NVE benefits from the advantages of DASH: it offers a scalable, easy-to-deploy 3D streaming framework. In our system, the 3D content is first statically partitioned into compliant DASH data, and metadata is provided in order for the client to manage which data to download. Based on a proposed utility metric for geometry and texture at the different resolution, the client can choose the content to request depending on its viewpoint. We effectively provide a Web-based client to navigate through our sample 3D scene, while deriving the streaming requests from its computation of the necessary online parameters, in a receiverdriven manner.
