The WRL (or VRML) file format is used to store 3D models and their environments in a simple-to-edit, plain text format. The WRL format has been around since the 1990s and has gained widespread support as a convenient 3D graphics format.
The 3D data is stored within the file in a hierarchical format, allowing 3D objects to be grouped and manipulated together. The format also allows 3D objects to be assigned unique IDs, allowing them to be referenced elsewhere in the same document, allowing the same 3D model to be used multiple times while only defining its vertices, faces, and other 3D data once.
While the format still enjoys support within many 3D editing applications, the WRL format has been officially superseded by the XML-based X3D format, which comes with more features and, with its use of the standard XML format, more support amongst 3D modelling applications.
WRL Converter Capabilities
When converting 3D model or mesh files using our WRL 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.
