The X3D format is similar to the older WRL 3D modelling 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 colour materials into a suitable format for use in the converted file.

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.
The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.
One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colours down to 256 or 16 colours to help reduce the file size of the PNG.
