| Description | STL is a file format native to the stereolithography CAD software created by 3D Systems. 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. | Written using VRML (Virtual Reality Modeling Language) file with virtual world that may be navigated in three dimensions. This file stores coordinates and colors that specify every object and shape and contains the viewpoint coordinates for the initial view of the three-dimensional scene. VRML files are commonly called "worlds" and have the .wrl extension (for example, island.wrl). VRML files are in plain text and generally compress well using gzip, useful for transferring over the internet more quickly (some gzip compressed files use the .wrz extension). Many 3D modeling programs can save objects and scenes in VRML format. |
| 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. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary. | |
