The VRML (or WRL) file format is used to store 3D models and their environments in a simple-to-edit, plain text format. The VRML 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While the format still enjoys support within many 3D editing applications, the VRML format has been officially superseded by the XML-based X3D format, which comes with more features and, with its use of the standard XML format, more support amongst 3D modeling applications.
VRML Converter Capabilities
Our VRML 3D Model/Mesh tool does not support any color material data contained within VRML files, so the converted file will not contain any color information.
The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.
As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.
The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

Our 3D conversion tool does not support color or material information in OBJ files, so your file will not contain any color information.
