Information about 3DS and STL file formats

🔸 File format 3DS STL
🔸 Full name Autodesk 3D Studio Max Stereolithography File Format
🔸 File extension .3ds .stl
🔸 MIME type application/x-3ds, image/x-3ds model/stl, model/x.stl-ascii, model/x.stl-binary
🔸 Developed by Autodesk Inc. 3D Systems
🔸 Type of format
🔸 Description 3DS is one of the file formats used by the Autodesk 3ds Max 3D modeling, animation, and rendering software. It was the native file format of the old Autodesk 3D Studio DOS, which was popular until its successor replaced it in April 1996. Since 1990, it has grown to become a de facto industry standard for transferring models between 3D programs or storing models for 3D resource catalogs. While the 3DS format aims to provide an import/export format, retaining only essential geometry, texture, and lighting data, the related MAX format also contains extra information specific to Autodesk 3ds Max to allow a scene to be completely saved/loaded. 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 3ds is a binary file format. The format is based on chunks, where each section of data is embedded in a block containing a chunk identifier and the length of the data and the data itself. This allows parsers to skip chunks they don't recognize and allows for extensions to the format. The chunks form a hierarchical structure, similar to an XML DOM tree. The first two bytes of the chunk are its ID. The parser can identify the chunk from that value and decide whether it will parse it or skip it. The next four bytes contain a little-endian integer that is the length of the chunk, including its data, the length of its sub-blocks, and the 6-byte header. The next bytes are the chunk's data, followed by the sub-chunks, in a structure that may extend to several levels deep. 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.
