Information about X3D and STL file formats

🔸 File format X3D STL
🔸 Full name Extensible 3D (X3D) Graphics Stereolithography File Format
🔸 File extension .x3d .stl
🔸 MIME type model/x3d+xml model/stl, model/x.stl-ascii, model/x.stl-binary
🔸 Developed by Web3D Consortium 3D Systems
🔸 Type of format
🔸 Description Extensible 3D (X3D) Graphics is the royalty-free open standard for publishing, viewing, printing, and archiving interactive 3D models on the Web. 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.
