Caligari TrueSpace COB File Format
The COB file format was developed by Caligari Corporation for its 3D modeling and animation software, TrueSpace. COB files store complete 3D scene data including geometry, materials, textures, lights, and animation. Though TrueSpace is now discontinued, COB remains an essential format for preserving and converting legacy 3D content.
Key Features of COB Files
- Full 3D Scene Storage: COB files encapsulate entire scenes with objects, lighting, cameras, and animation data.
- Two Format Variants:
- ASCII COB: Human-readable format ideal for manual inspection and debugging.
- Binary COB: Compact format optimized for performance and faster loading times.
- Material & Texture Support: Includes surface colors, image textures, and basic shading information.
- Geometry Types: Supports both NURBS-based and polygon mesh 3D models for greater flexibility.
COB File Conversion Tools
Use Autoconverter and Automesher Application to import and convert COB files into modern 3D formats such as FBX, OBJ, SKP, STEP, and SAT. Our converters retain crucial data including UV mapping, materials, and mesh topology by utilizing the Open Asset Import Library (Assimp) for accurate and reliable file processing.
Note: COB files can only be imported - exporting to COB format is not supported.
Rhinoceros 3D (3DM) File Format
The 3DM file format is the native format for Rhinoceros 3D (Rhino), a leading NURBS-based 3D modeling software used across industries like architecture, engineering, and industrial design. 3DM files accurately store mathematical representations of curves, surfaces, solids, and meshes, making them essential for precision 3D modeling and CAD workflows.
Key Features of 3DM Files
- NURBS Geometry: Supports precise, smooth surfaces critical for advanced design and engineering projects.
- Polygonal Meshes: Stores tessellated 3D models ideal for rendering, simulation, and 3D printing workflows.
- SubD Surfaces: Allows flexible, editable subdivision modeling for organic shapes and complex surfaces.
- Instance References: Saves memory by creating linked object instances, optimizing large and detailed models.
Convert 3DM Files Seamlessly
Autoconverter and Autoshaper simplify 3DM file conversion to popular formats like STEP, IGES, OBJ, STL, and DWG. Automate the export of 3DM polygon meshes for 3D printing, or preserve NURBS data for engineering-grade CAD models. Save files in legacy (Rhino 2.X - 7.X) or latest Rhino 8.X formats to ensure compatibility across all project environments.
