The X3D format is similar to the older WRL 3D modeling format, updated with more features and using a more modern XML file structure. It is designed for describing website virtual worlds.
As it was designed to be the successor to the WRL format, the X3D format supports most of the same capabilities, such as 3D mesh definitions via elements such as the IndexedFaceSet, which comprises geometrical vertices, faces, normals, texture coordinates, and more.
Due to the use of XML to store 3D information, files can grow quite large with complex 3D models. Support for X3D has been mixed, with some 3D editing applications building in access to the format and others mostly ignoring it in favor of other formats such as FBX and GLB.
X3D Converter Capabilities
When converting 3D model or mesh files using our X3D converter, we will attempt to convert color materials into a suitable format for use in the converted file.

An MP4 file is a modern standard format for storing high-quality motion video in a highly compact and efficient file size. The specific compression algorithm used within an MP4 file can vary from file to file; however, they all enable what would otherwise be a large amount of uncompressed data to be reduced to a fraction of the original size with little or no noticeable difference in playback quality.
Due to their widespread support, MP4 files can be loaded into most video editing applications and played with most video playback software with no additional drivers. Most video sharing sites, such as YouTube, support MP4 as a format when uploading, and most tablets and smart phones can record in the MP4 format.
Audio stored within an MP4 file is usually stored in the MP3 format, taking advantage of that format's high quality and compression capabilities.
