3D printing can be an expensive process, and simulation models exist to predict how a printed object would look like. To visualize such simulated objects, the cuttlefish 3D printing project uses X3DOM.

Getting CAD models visualized on the Web usually requires some work, as CAD representations, such as BReps, differ from visualization formats, such as X3DOM’s BinaryGeometry or the X3D IndexedFaceSet.
To solve problems like this, you can use PythonOCC, a python package that comes with powerful CAD functionality. This includes, for instance, exporting STEP to X3D with just a few lines of code.
For a quick look, check out some simple examples here!
The American National Institute of Standards and Technology (NIST) has just made public an X3DOM version of the Digital Library of Mathemetical Functions (DLMF). VRML content has been successfully migrated to X3DOM, so that every WebGL-capable browser can now be used to inspect high-quality visualizations of mathematical functions from the DLMF.
Here are some starting points to get an impression:
We added the Siena Cathedral to the showcases. The demo comes with a nice animated camera flight through the wonderful building. In the near future, we hope to add more showcases and demos to the dedicated demo page, which is currently http://examples.x3dom.org/.
The Siena Cathedral can be found here.
Another Fraunhofer project uses X3DOM to render a 3D web visualization: CityServer3D. The technology of the CityServer3D consists of a geo-database, a server with numerous interfaces for the import and export of the data and applications for the development of landscape models. This data can also be presented in a web browser using X3DOM to render the visualization. For instance, the city of Darmstadt:
This representation has been rendered using the CityServer3D VIEW Service which provides complete 3D GIS applications based on integrated 2D and 3D data. Moreover, it offers direct access to geodata via a powerful web service interface.
You can do this of course with arbitrary hardware (think of the LEAP support or the Kinect), but please bear in mind that this is only a preview at the moment.
You can find the tutorial here. Enjoy!
VRMath 2.0 (VRMath2) is a Virtual Reality learning environment (VRLE) and an online learning community. It employs the powerful ideas of 3D Logo Microworld and Web 2.0 technologies for learning mathematics and was created by Andy Yeh, Australia.
In VRMath2, everyone can Design, Create and Share their 3D virtual worlds. There are also design challenges you can take up and blog later right here in VRMath2 website.
The scalable SimScale platform uses X3DOM as viewer frontend for visualizing the results of online numerical simulations on CAD data.
Yet another interesting industrial show case from Frank Lamack, T-Systems, Germany. Goal of this solution is to build a web 3d based environment for distributed teams to enable collaborative design reviews or co-browsing with customers for sales, configuration and consulting sessions – on one common 3d product model: Without any plug-in or additional software licences – simply via web. Upcoming features: dimensioning, annotation on parts or co-design-editor, to transform 3d-shapes.
T-Systems Multimedia Solutions (MMS) develops web-based solutions for large corporations and medium-sized enterprises. Around 1.000 employees serve customers from every sector, developing web innovations for services used in domestic and commercial digital contexts. This includes e-commerce, information management and knowledge management. The actual developing team develops visual configuration solutions, that use 3D construction data and product meta data in combination with rule-based configurations for immersive e-sales and e-commerce applications for web or mobile devices.
This external showcase developed by the Virtual Reality Center Production Engineering (VRCP) in cooperation with the Fraunhofer Institute for Machine Tools and Forming Technology (IWU) shows an innovative way to present complex content with the use of 3D models. 3DWebpresenter makes it obvious that X3DOM can also visualize complex 3D scenes combined with interactive Web elements. While navigating intuitively through a virtual factory, further information of the results of 30 projects of the Innovation Alliance “Green Carbody Technologies” can be accessed.
When using declarative 3D approaches for the rendering of large models, it is crucial to externalize vertex data from the HTML document by using binary containers (see previous post). Attribute data can be concurrently fetched by the Browser via Ajax calls or image downloads and is directly transferred as-is to GPU memory for rendering. Such a straightforward approach significantly reduces the memory and processing overhead, which is especially of high importance on mobile devices with limited CPU power.
A new X3DOM example, which uses the BinaryGeometry node, demonstrates how a compact vertex data representation for efficient visualization of large models can look like.
We furthermore improved our culling and mesh compression techniques to get the famous Boeing 777 model running at interactive frame rates. This “out-of-browser”-based hybrid client/server approach allows rendering 350 million triangles, where a special out-of-core server constantly streams up to 9 million triangles to the client. The results are not yet final, but the current state shows that the method scales and we can handle models even of the size of the 777. And here is the link to the video: http://www.youtube.com/watch?v=4TrJBsb74f0
The X3DOM showcases reported here have largely been centered around industrial or scientific applications. However there’s a lot of potential for commercial applications that has not been explored yet. As the framework matures, it is much more interesting and usable for larger deployments.
One example of such an application is Mixee Me. A recent startup which sets out to bring 3D printing to the average joe. The gist: Mixee Mee allows everyone to create funny little 3D characters through a simple interface, have them printed with a 3D printer and shipped to your doorstep. In order to allow for online composition of the 3D figures, X3DOM ist used to drive the interface.
We are going to present the paper with the longest title we’ve ever produced at the Web3D 2012 conference taking place in four weeks in LA: “Using Images and Explicit Binary Container for Efficient and Incremental Delivery of Declarative 3D Scenes on the Web“. It’s all technology to build fast and responsive X3DOM applications. We are going to release the final code as part of X3DOM and a command line tool to convert the mesh data easily before the event. In the meantime please enjoy some more demos that utilize the new binary mesh container.
Applications to experience cultural heritage objects seem to be really popular inside of the x3dom community :). There is another 3D gallery for scanned historical objects.
This external show-case is from Anestis Koutsoudis, Cultural and Educational Technology Institute – Research Centre ‘Athena’, and includes a nice 2D-UI to browse the different models.
Another excellent external showcase that provides an x3dom integration is OpenCart, which is a powerful and easy to use open source shopping card system.
The latest version of the code now supports X3D as media type and uses x3dom for online visualization.
