“…Since the use of OpenGL commands needs advanced programming skills, there have been several actions to provide an "interface" between them and the creation of web pages. We could subdivide the proposed systems between declarative approaches [Jankowski et al 2013], like X3DOM [Behr et al 2009] or XML3D [Sons et al 2010], and imperative approaches, like Three.js [Dirksen 2013], SpiderGL [Di Benedetto et al 2010] and WebGLU [DeLillo 2009]. The main difference between the groups is that the first ones rely on the concept of scenegraph, hence a scene has to be defined in all its elements, while the second ones provide a more direct interface with the basic commands.…”

Figure 1: Progressive refinement of the Happy Buddha: on the upper left corner the size downloaded, on the upper right corner the number of triangles in the refined model. The header and index amount to 8KB AbstractEfficient transmission of 3D data to Web clients and mobile applications remains a challenge due to limited bandwidth. Most of the research focus in the context of mesh compression has been on improving compression ratio. However, in this context the use of Javascript on the Web and low power CPUS in mobile applications led to critical computational costs. Progressive decoding improves the user experience by providing a simplified version of the model that refines with time, and it's able to mask latency. Current approaches do so at very poor compression rates or at additional computational cost. The need for better performing algorithms is especially evident with this class of methods where Limper [Limper et al. 2013b] demonstrated how decoding time becomes a limiting factor even at moderately low bandwidths. In this paper we present a novel multi-resolution WebGL based rendering algorithm which combines progressive loading, view-dependent resolution and mesh compression, providing high frame rates and a decoding speed of million of triangles per second in Javascript. This method is parallelizable, robust to non-manifold meshes, and scalable to very large models.

“…WebGL has been used for real time 3D visualization over the web, which is an imperative approach to 3D web graphics [Jankowski et al 2013;Coughlin 2014]. It uses the HTML5 canvas element and JavaScript to expose low level graphics API which is based on OpenGL ES 2.0 (a restricted version of the OpenGL API, originally designed for embedded systems, but capable of compiling vertex and fragment shaders).…”

The main motivation of this paper is to provide a current state and a brief overview of animation on the web. Computer animation is used in many fields and it has seen a lot of development in the recent years. With the widespread use of WebGL and the age of powerful modern hardware available on small devices, 3D rendering on the browser is now becoming commonplace. Computer Animation can be described as the rendering of objects on screen, which can change shape and properties with respect to time. There are many approaches to rendering animation on the web, but none of them yet provide a coherent approach in terms of transmission, compression and handling of the animation data on the client side (browser). And if computer animation has to become more accessible over the web, these challenges need to be addressed in the same "minimalistic manner (requirement wise)" as every other multimedia content has been addressed on the web. We aim to provide an overview of the current state of the art, while commenting on the shortcomings pertaining to current formats/approaches and discuss some of the upcoming standards and trends which can help with the current implementation.

“…Embedding the 3D content directly into HTML(5) documents is currently done by using a so-called "polyfill" layer to mimic native web browser support [9]. Therefore, online 3D museum applications can easily be implemented by a web developer instead of graphics experts.…”

Internet services are becoming more ubiquitous and 3D graphics is increasingly gaining a strong foothold in the Web technology domain. Recently, with WebGL, real-time 3D graphics in the Browser became a reality and most major Browsers support WebGL natively today. This makes it possible to create applications like 3D catalogs of artifacts, or to interactively explore Cultural Heritage objects in a Virtual Museum on mobile devices. Frameworks like the open-source system X3DOM provide declarative access to low-level GPU routines along with seamless integration of 3D graphics into HTML5 applications through standardized Web technologies. Most 3D models also need to be optimized to address concerns like limited network bandwidth or reduced GPU power on mobile devices. Therefore, recently an online platform for the development of Virtual Museums with particular attention to presentation and visualization of Cultural Heritage assets in online virtual museums was proposed. This common implementation Framework (CIF) allows the user to upload large 3D models, which are subsequently converted and optimized for web display and embedded in an HTML5 application that can range from simple interactive display of the model to an entire virtual environment like a virtual walk-through. Generating these various types of applications is done via a templating mechanism, which will be further elaborated within this paper. Moreover, to efficiently convert many large models into an optimized form, a substantial amount of computing power is required, which a single system cannot yet provide in a timely fashion. Therefore, we also describe how the CIF can be used to utilize a dynamically allocated cloud-based or physical cluster of commodity hardware to distribute the workload of model optimization for the Web
