The Standard Template Library (STL) is a software library originally designed by Alexander Stepanov for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithms , containers , functions , and iterators .
STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.
The size of the vector refers to the actual number of elements, while the capacity refers to the size of the internal array. When new elements are inserted, if the new size of the vector becomes larger than its capacity, reallocation occurs. [1] [5] This typically causes the vector to allocate a new region of storage, move the previously held ...
This W3C-unspecified vector image was created with Inkscape. This file supersedes the file STL-file.jpg . It is recommended to use this file rather than the other one.
In adapting STL to be included in the C++ Standard Library, Stepanov worked closely with several members of the standards committee, including Andrew Koenig and Bjarne Stroustrup, who observed that custom allocators could potentially be used to implement persistent storage STL containers, which Stepanov at the time considered an "important and ...
SVG – Scalable Vector Graphics, employs XML; 3DMLW – Scene description languages (3D vector image formats) STL – Stereo Lithographic data format (see STL (file format)) used by various CAD systems and stereo lithographic printing machines. See above.

STL files recreate the geometry of a 3D CAD model using a mesh of triangles, which approximate the shape of the object. Each triangle is defined by three vertices and a normal vector that indicates the direction of the outer surface (due to the Right-Hand Rule ). [ 5 ]
