Architecture, engineering and construction (AEC) has witnessed a boom in the use of web3d technologies over the past few years thanks to the proliferation of webGL support in modern web browsers, and the ever increasing need for multidisciplinary collaboration across large-scale construction projects. In this summary, we present a number of AEC-specific requirements and a set of applications for interactive visualization via the Internet based on the 3d Repo open source platform. These span collaborative design, 3d change and clash detection, data mining, maps integration and health and safety training. The presented use cases were developed in collaboration with large AEC companies, namely Atkins, Balfour Beatty, Canary Wharf Contractors, Costain and Skanska in the UK.

How to model and visualize a large scale forest scenes in a realistic and lightweight way keeps to be an important problem in web3d Game and VR applications. This paper presents a novel solution to real time web3d visualization of huge forest scenes. The data size of huge forest scenes is reduced to very low level by reusing some branches repetitively, thus, which can be transmitted over mobile Internet and renderedweb3d browsers instantly. However, the visual morphology and shaping variety of huge forest scenes can still be preserved with more straightforward hierarchical rules than L-System. From one sampling tree, we can extract it rules and grow them randomly to model large scale virtual forest scenes and render them lightweightly at web3d browsers. Experimental Results show our proposed method outperform the existing web3d forest modeling and rendering methods in terms of data volume, shaping polymorphism, networking bandwidth andweb rendering and achieves instant web3d visualization of huge forest.

In this paper, we present the pipeline of animated3dweb content creation, which is based on semantic composition of 3d content activities into more complex animations. The use of knowledge representation adapts the approach to the current trends in the webdevelopment and enables modeling of animations using different concepts, at arbitrary abstraction levels, which makes the approach intelligible to domain experts without technical skills. Within the pipeline, we use the OpenStage 2 motion capture system and the Unity game engine.

In this poster, we present a virtual car showroom. The use of virtual and augmented reality (VR/AR) becomes increasingly popular in various application domains, including prototyping, marketing and merchandising. In car industry, VR/AR systems enable rapid creation and evaluation of virtual prototypes by domain specialists as well as potential customers. In this work, we present a virtual car showroom implemented using the Unity game engine, an HMd and a gesture tracking system. The application enables immersive presentation and interaction with 3d cars in a virtual environment.

We present the instant3dhub(1) solution as a showcase on the use of today's web technologies for connecting business data and3ddata in the context of PLM systems and modern service platforms or cloud environments. This solution allows companies to easily enrich their applications and workflows with 3d visualization in a non-invasive way. Concepts and benefits are illustrated by examples of successfully integrated solutions.

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.

With a view to investigate, examine and analyze the performance of 3d medical image compression based on Autoencoder neural networks, a novel algorithm named autoimage reconstruct algorithm is developed, which is based on recent BAT bioinspired algorithm with a novel fitness function as Mean Square Error. It is observed that proposed algorithm outperforms existing algorithms like wavelet-based encoding anddecoding for image compression and reconstruction in terms of Mean Square Error, Peak Signal to Noise Ratio (PSNR) and Compression Ratio (CR).

disappeared buildings in university campus is always an unforgotten memory for alumnus. The authors developed a web application to allow users to view the historical 360 degree spherical panoramas when approaching the GPS location of the historical anddisappeared campus scenery. A spherical panoramas database of the campus were recordedduring the past 20 years from spring to winter and important events, thus it could provide a multi-dimensional memories for various alumnus through the AR interface.
