What is a .VTK file?
VTK stores 3D scientific data for the Visualization Toolkit.
- Did you know
- The Visualization Toolkit, released as open source in the mid-1990s, powers much scientific 3D visualisation.
- VTK was created in 1993 by three GE Research engineers who later founded Kitware, the company that now maintains it, and it comes in two flavours - the simple legacy .vtk text format and a newer XML-based family.
- The toolkit defines five dataset types, including image data, structured grids and unstructured grids, each with its own modern extension.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .VTK is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .VTK file
- Drag a .VTK file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
