The VTP file format is the successor to the older VTK format. Updated to store data in a structured XML format rather than the bespoke plain text structure of the VTK format. The same 3D elements that could be stored within a VTK file can be transferred to the VTP format.
As VTP files are based on plain text XML, binary 3D model data can be encoded using the Base64 encoding method, which allows binary data to exist within plain text structures such as XML. This binary model data consists of common 3D geometric elements such as vertices, faces, and surface material information.
The VTP format also allows 3D model data to be stored in a compressed format prior to the Base64 encoding process to help reduce the overall file size. VTP files can be imported into several 3D editing applications, and we have a set of VTP conversion tools to convert these files to other popular 3D formats, such as STL.
VTP Converter Capabilities
Our VTP 3D Model/Mesh tool does not support any color material data contained within VTP 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.
