.X3D File

The x3d file extension is associated with X3D, a scalable and open software standard for defining and communicating real-time, interactive 3D content for visual effects and behavioral modeling. It can be used across hardware devices and in a broad range of applications including CAD, visual simulation, medical visualization, GIS, entertainment, educational, and multimedia presentations.

X3D provides both the XML-encoding and the Scene Authoring Interface (SAI) to enable both web and non-web applications to incorporate real-time 3D data, presentations and controls into non-3D content.

X3D is the successor to the Virtual Reality Modelling Language (VRML). It improves upon VRML with new features, advanced APIs, additional data encoding formats, stricter conformance, and a componentized architecture using profiles that allows for a modular approach to supporting the standard and permits backward compatibility with legacy VRML data.

Files with x3d file extension can be found as 3D models or other graphics interactive content based on X3D standard.

How to open:

You can for example use the X3D-Edit tool by Don Brutzman to open and edit *.x3d models. However, you also find other programs capable of of working with this format.

How to convert:

Some dedicated 3D model translators support X3D format and can translate models between various formats.
