glTF/X3D Comparison

WIth 3D/VR becomming practical in the web browser there are a lot of questions concerning the right format to use for various situations. This post looks at two model formats - X3D and glTF. Both formats support full geometric surface modeling, but there are differences between these formats for some specific areas.

Integrating X3D into DOM - Case Sensitivity

The X3D language uses mixed case node and field names. In some cases field values are specified as case-specific names. This is standard XML. HTML allows for any case and converts tags and attribute names to lower case before use. The HTML language does not impose specific case requirements on attribute values. XHTML is XML-based, so it is case sensitive; however, all tag and attribute names are defined as lowercase.

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: 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.

Report from SVVR2017

I attended my first Silicon Valley VR Expo last week. It was very different than VRLA. As might be expected, this one is more focused on tech; though there were plenty of content discussions. Fortunately, the expo floor was not as loud as VRLA and I had many conversations with vendors.
