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. So getting right to the comparison, the following table lists a number of features that are needed or desirable for the display of 3D models in either a flat-screen or VR/xR approach. Certain capabilities are explicitly not included in the table such as lighting or background.

 The big announcement this month from Khronos is Blender now exports glTF models. Things makes a very large collection of models now available for use in web pages with libraries like XSeen.

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.

Main post that lists the major issues for integration.

The previous post ("Integrating X3D Into DOM - Inline") developed a solution for namescoped nodes, specifically Inline. This post looks at implications of that solution.

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.

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.

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.
