VTK files (Visualization Toolkit) are a 3D graphics format used to store 3D models and scientific visualizations in a format that is easy to integrate into 3D rendering systems.
The VTK format consists of a header section that describes the data structure and fields present in the main content. The actual 3D content can be stored as either plain ASCII text or binary, with the binary option offering the most efficient use of storage space.
There are several VTK viewing applications available, and our own set of VTK conversion tools can convert to and from other common 3D formats, such as OBJ.
VTK Converter Capabilities
Our VTK 3D Model/Mesh tool does not support any color material data contained within VTK 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.
OBJ Converter Capabilities
Our 3D conversion tool does not support color or material information in OBJ files, so your file will not contain any color information.
