The VTK file format is a 3D modeling and graphics format supported by the Visualization Toolkit. Created in the '90s, the Visualization Toolkit provides a series of data and visual tools for advanced 3D modeling applications. Some example functions of the toolkit include polygon simplification, mesh repair and smoothing, and more.
The format has evolved over the years. It started out as a simple text-based format that could be edited within a simple text editor. Additional features have been added over the years, with the most recent version of the format supporting an XML-based format.
Here we have some example VTK files for you to download and use in your own projects.
Cube
The classic cube example is stored as a VTK file. Within the VTK file, this cube is stored as a sequence of 12 triangles.
Swirl
A simple swirl 3D model that was generated using our PNG to VTK tool using Extrude mode.
