Information about VTK and STL file formats

🔸 File format VTK STL
🔸 Full name Visualization Toolkit Data File Stereolithography File Format
🔸 File extension .vtk .stl
🔸 MIME type application/octet-stream model/stl, model/x.stl-ascii, model/x.stl-binary
🔸 Developed by Kitware Inc. 3D Systems
🔸 Type of format
🔸 Description The Visualization Toolkit (VTK) is open-source software for manipulating and displaying scientific data. It comes with state-of-the-art tools for 3D rendering, a suite of widgets for 3D interaction, and extensive 2D plotting capability. VTK is part of Kitware's collection of supported platforms for software development. The platform is used worldwide in commercial applications, as well as in research and development. STL is a file format native to the stereolithography CAD software created by 3D Systems. Many other software packages support this file format. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common since they are more compact.
🔸 Technical details An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. As a result, STL files contain no scale information, and the units are arbitrary.
