STL (file format)
STL (STereoLithography) is a file format native to the stereolithography CAD software created by 3D Systems. STL has several after-the-fact backronyms such as "Standard Triangle Language" and "Standard Tessellation Language". This file format is supported by many other software packages; 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 any representation of 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.
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. STL coordinates must be positive numbers, there is no scale information, and the units are arbitrary.
Usage examples of "stl".
The fans were stl too, although the weather had changed sharply overnight, the thick muggy air blown away and replaced by one of those clear blue-and-white days that were more spring than summer, so that, like Nadine, she wore a sweater buttoned over her blou ise.
There was no mention of current position--the family was recorded as being active in stl, slip, and rl-est.
