Virtual Reality provides a unique opportunity to improve modern production planning processes. Using the first-person perspective and users body as the source of realistic constrains, any user can experience the design challenges at a given workstation. By grounding VR User Experience design in embodiment theories, we propose a new paradigm of human-in-the-loop for production planning. We call it Embodied Engineering (EE).

Interactive 3D content gains increasing use in VR/AR applications in different domains, such as education, training, engineering, spatial and urban planning as well as architectural and interior design. While modeling and presenting interactive 3D scenes in collaborative VR/AR environments, different 3D objects are added, modified and removed by different users, which leads to the evolution of the scenes over time. Representation of VR content covering temporal knowledge is essential to enable exploration of such time-dependent VR/AR content. However, the available approaches do not enable exploration of VR content with regards to its time-dependent components and properties, which limits their usage in web-based systems. The main contribution of this paper is 4--dimensional representation of VR content, which encompasses time being the fourth dimension. The representation is based on the semantic web standards and ontologies, which enable the use of domain knowledge for collaborative creation and exploration of content. This could improve the availability of VR/AR applications to domain specialists without expertise in 3D graphics and animation, thus improving the overall dissemination of VR/AR on the web. The representation has been implemented in a heterogeneous collaborative VR environment for urban design.

We study depth map reconstruction for a specific task of fast rough depth approximation having sparse depth samples obtained from low-cost depth sensors or SLAM algorithms. We propose a model interpolating downsampled semi-dense depth values and then processing super-resolution. We study our method in comparison with the state-of-the-art approaches transferring RGB information to depth. It appears that the proposed approach can be used to approximately estimate high-resolution depth maps.

The rapid digitalization of the Facility Management (FM) sector has increased the demand for mobile, interactive analytics approaches concerning the operational state of a building. These approaches provide the key to increasing stakeholder engagement associated with Operation and Maintenance (O&M) procedures of living and working areas, buildings, and other built environment spaces. We present a generic and fast approach to process and analyze given 3D point clouds of typical indoor office spaces to create corresponding up-to-date approximations of classified segments and object-based 3D models that can be used to analyze, record and highlight changes of spatial configurations. The approach is based on machine-learning methods used to classify the scanned 3D point cloud data using 2D images. This approach can be used to primarily track changes of objects over time for comparison, allowing for routine classification, and presentation of results used for decision making. We specifically focus on classification, segmentation, and reconstruction of multiple different object types in a 3D point-cloud scene. We present our current research and describe the implementation of these technologies as a web-based application using a services-oriented methodology.

Geometric acoustics is one of the most commonly used techniques for exploring what a virtual environment sounds like. These methods allow the user to place a sound source and receiver in a space and compute how the space influences what the receiver hears. These simulation methods are well-known, but most are proprietary or difficult to implement. We present a web-based simulator that enables anyone with an internet connection to hear a virtual space quickly and easily. Our simulator is written in C++ and compiled to javascript for use in all major web browsers.

In this paper we describe a semantic approach to visualization of 3D cyberspace of scientific papers and their research front using web-based 3D graphic. The most cited and significant documents in this cyberspace are represented by spheres of a large size and the distance between documents is proportional to their semantic similarity. A new measure of semantic similarity of documents is proposed that is determined by the maximum correlation between explicit and implicit connectivity of the documents. A new science contextual citation index (SCCI) that is defined by a correlation maximum with a science citation index (SCI) is proposed and implemented. SCCI can more accurately measure scientific impact, find significant documents and evaluate new articles with zero SCI. Significant similar articles confirm each other and form clusters in the cyberspace. Research front exists as a set of such clusters. The proposed cyberspace implemented by WebVR and interactive 3D graphics can be considered as a dynamic learning environment that is convenient for discovering new significant articles, ideas and trends. It can be a powerful tool of information integration, because it allows you to visualize documents of different languages in a single space.

Collaborative engineering design is a time-consuming process because the collaborative partners are spatially distant and familiar with divergent software solutions due to their local circumstances. The data compatibility problem rises between collaborating groups because each group uses a particular software solution that is different from other groups. A platform independent web-based solution for collaborative CAD system, that supports files of multiple CAD systems as well, has been implemented in this paper. The implemented solution saves time by providing web-based editing and visualization and preserves the design intent that makes it reusable.

In this poster, we present a configurable virtual reality store. The virtual store may be displayed using immersive VR systems, such as a CAVE or an HMD, to enable merchandising research, or on the web to enable creation of 3D e-commerce applications. In the proposed solution, the visualized shopping space is created dynamically as a combination of three elements: virtual exhibition model, product models and virtual exhibition data, enabling easy configuration of exhibitions by domain experts and researchers.
