What is X3D?

X3D is:

• A simple text language for describing 3-D shapes and interactive environments
• X3D text files use a .x3d, x3dj, x3dv, or .x3db extension
  • .x3d (XML) - save to parse
  • .x3dj (JSON) - good for scripting
  • .x3dv (VRML) - easy to learn
  • x3db (Binary) - good for large models

Note: all examples are in X3D Classic Encoded file format (.x3dv).

What do I need to use X3D?

You can view X3D files using a X3D browser:

• A X3D standalone application
• A X3D JavaScript plug-in like to an HTML browser

You can view X3D files from your local hard disk, or from the Internet.

How can X3D be used on a Web page?

• Fill Web page
• Embed into Web page
• Fill Web page frame
• Embed into Web page frame
• Embed multiple times

What do I need to develop in X3D?

You can construct X3D files using:

• A text editor
• A authoring tool
• A 3D modeler and format translator
• A shape generator (like a Python, or Perl script)

Should I use a text editor?

Pros:

• No new software to buy
• Access to all X3D features
• Detailed control of world efficiency

Cons:

• Hard to author complex 3D shapes
• Requires knowledge of X3D syntax

Should I use a authoring tool?

Pros:

• Easy 3-D drawing and animating user interface
• Little need to learn X3D syntax

Cons:

• May not support all X3D features
• May not produce most efficient X3D

Should I use a 3D modeler and format translator?

Pros:

• Very powerful drawing and animating features
• Can make photo-realistic images too

Cons:

• May not support all X3D features
• May not produce most efficient X3D
• Not designed for X3D
• Often a one-way path from 3D modeler into X3D
• Easy to make shapes that are too complex

Should I use a shape generator?

Pros:

• Easy way to generate complex shapes
• Fractal mountains, logos, etc.
• Generate X3D from PHP scripts
• Common to extend science applications to generate X3D

Cons:

• Only suitable for narrow set of shapes
• Best used with other software
