Recent advances in 3d imaging techniques allow detailed representations of the anatomy of animals and are an important tool in comparative morphology. However, the volume data are rather large and require special programs for visualization. A web based interface is created to allow inspection of volume data for everybody directly in a browser. We currently host more than 6000 CT datasets;each of it can be inspected and sub-volumes can be requested and viewed in a high resolution within one second response time. Our system offers direct visualization of high resolution volume data which hopefully will find broad applications in science and education.

For many computer vision applications, the availability of camera calibration data is crucial as overall quality heavily depends on it. While calibration data is available on some devices through Augmented Reality (AR) frameworks like ARCore and ARKit, for most cameras this information is not available. therefore, we propose a web based calibration service that not only aggregates calibration data, but also allows calibrating new cameras on-the-fly. We build upon a novel camera calibration framework that enables even novice users to perform a precise camera calibration in about 2 minutes. this allows general deployment of computer vision algorithms on the web, which was previously not possible due to lack of calibration data.

We introduce a novel method for rectangular selection of components in large 3d models on the web. Our technique provides an easy to use solution that is developed for renderers with partial fragment shader support such as embedded systems running webGL. this method was implemented using the Unity 3d game engine within the 3d Repo open source framework running on a web browser. A case study with industrial 3d models of varying complexity and object count shows that such a solution performs within reasonable rendering expectations even on underpowereddevices without a dedicated graphics card.

As 3d on the web gains momentum via standards such as webGL andwebXR, a reoccurring frustration among webdevelopers is inability to leverage 2dweb technologies within immersive presentation contexts. the use-cases for blending 2d and3dweb content include progressive enhancement of 2dweb pages, re-use of existing 2dweb content, and layout/design of complex interactive user interfaces for 3d environments. We introduce webLayer3d, a JavaScript plugin for *** (a popular 3d scene-graph library) that makes it easy for webdevelopers to integrate live interactive 2dweb content (built using standardweb technologies) into a 3d scene (rendered using webGL). In this paper, we demonstrate that existing dOM-to-Texture techniques (when usedthoughtfully) are sufficient for enabling a performant, flexible, and simple approach to building interactive 3d user interfaces for the immersive web.

this paper introduces a web application for point cloud annotation that is used in the advanceddriver assistance systems field. Apart from the point cloud viewer, the web tool has an object viewer and a timeline to define the attributes of the annotations and a video viewer to validate the point cloud annotations withthe corresponding video images. the paper also describes several strategies we followed to obtain annotations correctly and quickly: (i) memory management and rendering of large-scale point clouds, (ii) coherent combination of video images and annotations, (iii) content synchronization in all parts of the application and (iv) automatic annotation before andduring the annotation task of the user.

A large number of sensors deployed in recent years in various setups andtheir data is readily available in dedicateddatabases or in the cloud. Of particular interest is real-time data processing and3d visualization in web-based user interfaces that facilitate spatial information understanding and sharing, hence helping the decision making process for all the parties involved. In this research, we provide a prototype system for near realtime, continuous X3d-based visualization of processed sensor data for two significant applications: thermal monitoring for residential/commercial buildings and nitrogen cycle monitoring in water beds for aquaponics systems. As sensors are sparsely placed, in each application, where they collect data for large periods (of up to one year), we employ a Finite differences Method and a Neural Networks model to approximate data distribution in the entire volume.

the web has been an extremely effective collaboration platform, enabling services like Wikipedia article co-authoring, blogging, social messaging, video conferencing, and many others. However, the collaboration should ideally occur Peer to Peer (P2P) among the participants instead of going through a centralized server as in the current centralizedweb, which acts as a mediator as well as a repository of data, especially for face-to-face collaboration in 3d XR context. Most notable XR applications like MMORPG have been developed in a dedicated application platform withtheir own centralized game servers. Nowadays, the decentralizedweb is being promoted as the next web architecture in numerous fronts such as blockchain in cryptocurrency, reviving P2P storage, and networking technologies as the next web, web3.0. It would be beneficial if we could make an XR collaboration framework based on the recent developments of the decentralizedweb. this paper explores one possible amalgamation of the decentralizedwebtechnology stack toward a webized XR collaboration framework.

We introduce a coding framework that supplements introductory computer graphics courses, withthe goal of teaching graphics fundamentals more effectively and lowering the excessive barrier of entry to 3d graphics programming. In particular, our framework provides ***, a new webGL-based software library for implementing projects, including an improved organization system for graphics code that has greatly benefited our students. To mitigate the difficulty of creating 3d graphics-enabledwebsites and online games, we furthermore introduce the "Encyclopedia of Code"-a World Wide web framework that encourages visitors to learn 3d computer graphics, build educational graphical demos and articles, host them online, and organize them by topic. Our own contributed examples include various interactive tutorials and educational games. Some of our modules expose students to new graphics techniques, while others explore new modes of online learning, collaboration, and computing. In comparison to earlier online graphics coding platforms and mainstream graphics educational materials, the resources that we have developed offer a significantly unique set of features for both inside and outside our classrooms.
