.3ds File — 3D Studio Mesh

3DS is a legacy 3D file format originating from Autodesk 3D Studio for DOS (pre-3ds Max), one of the earliest 3D modeling and rendering applications for personal computers. 3DS files store 3D mesh geometry, material definitions, texture mappings, cameras, lights, and basic keyframe animation using a chunk-based binary structure. The format supports polygon meshes with per-vertex colors, multiple UV mapping channels, and hierarchical object naming. 3DS was one of the first widely exchanged 3D file formats and established many conventions for 3D data interchange that influenced later formats. Despite significant limitations — no support for n-gons (only triangles), a 65,536 vertex limit per mesh, 8-character name limits, and no skeleton/bone animation — 3DS files remain encountered in legacy asset libraries, CAD conversion pipelines, and architectural visualization archives. The format's simplicity and wide support ensure that virtually every 3D application can import 3DS files. For new projects, modern formats like FBX, glTF, or COLLADA are preferred for their superior feature sets and lack of legacy limitations. 3DS importing is supported by Blender, Maya, 3ds Max, Unity, and most 3D tools.
