Introducing XSeen

HTML gained wide-spread acceptance because it was straight-forward and produced results even if you did write it perfectly - it is very forgiving. Of course, you get better results when written correctly, but you are never puzzling out what IEA102A INVALID PARAMETER/FORMAT - RESPECIFY means1. HTML presents a unified environment to the web designer and user.

XSeen

XSeen is a tool for the purpose of developing the next generation standard for declarative 3D and Virtual Reality content on the Web. It is designed to function completely integrated with the DOM and incorporate the best features of X3D, A-Frame, and other declarative 3D languages. It is written in JavaScript and built upon THREE.js. It is fully open source with the code base dual-licensed as MIT and GPL. The documentation is Creative Commons Share-Alike.

XSeen: Merging X3D and A-Frame

This post introduces XSeen - a declarative language built on A-Frame and X3D to achieve the desire of a fully declarative 3D/VR language that runs in the web browser. In this initial release the language supports some X3D and some A-Frame nodes and capabilities. It is possible to combine the two to produce results that are the available in either.

Purpose of X3D - Display

This is the fifth in a series discussing the next generation of X3D and addresses the needs and requirements for X3D for the display of 3D, AR, and VR content in the current ecosystem of display devices and environments. The 3D content is displaying in a larger ecosystem of including the user’s computer, browser, Internet, and originating server. As such it needs to work cooperatively within the environment and with other content already displaying in that environment.

Purpose of X3D - Archive

This is the fourth in a series discussing the next generation of X3D. Archiving and long-term storage has always been a strong point of X3D. The ability to read and play content from years or even decades ago makes it unsurpassed in the 3D world. X3D has human-readable formats that can be used for archiving so that the content does not require special software to unpack and display the file contents. It is important to keep the long-term storage and access capability while along X3D to stay current with advances in display technology.

Purpose of X3D - Architecture

This is the third in a series discussing the next generation of X3D. The current architecture of X3D does not support the industry standards in modeling, archival, and user experience. It uses a single primary file with additional external resources loaded as needed including other X3D files or media (images, audio, video, and scripts). The capabilities made available in the X3D files are either insufficient (e.g., lack of deformable skin animation) or in conflict with the major display environment (e.g., Scripts). This post describes a systems architecture with implications for content architecture that addresses these issues.

Purpose of X3D - Animation

This is one in a series examining the purpose of X3D - where is it's niche in the electronic ecosystem and what function does it perform. The series also looks at where X3D needs to evolve to best serve the ecosystem. This post looks at animation. It was motivated by issues involving deformable skins that are needed to animate non-mechanical models.

Purpose of X3D

X3D and VRML have been an international standard since 1997. They define a means to model and texture 3D geometry, animate it, and provide user interaction. As an International Standard (VRML: ISO/IEC 14772, and X3D: ISO/IEC 19775-19777) these have provided extraordinarly stable and long-lasting formats. Content developed 20 years ago still runs today. That is an important legacy that should not be lost. At the other end of the timescale (today), there are environments and capabilities that could not have been imagined when the first standard was approved. X3D needs to keep a foot in the ancient past (as far as computer time goes) and current so that history is not lost.
