COB Caligari TrueSpace Object File

A proprietary 3D file type created by Caligari Corporation for their TrueSpace modeling and animation software. This format was designed to store complete 3D scenes including geometry, materials, and animation data from TrueSpace projects. While the software is no longer actively developed, COb files remain important for working with legacy 3D assets and converting older TrueSpace creations to modern formats.

Key Features of COB

  • Complete 3D Scene Storage: COB files save entire 3D scenes including models, lights, and cameras in a single file.
  • COB File Formats: There are two types of COB files:
    • ASCII - Human-readable for manual edits and debugging in any text editor.
    • Binary - Smaller file sizes and faster loading for complex 3D scenes.
  • Material Support: The COB format stores color, texture, and basic material properties for 3D objects.
  • NURBS and Mesh Data: Supports both NURBS surfaces and polygonal mesh geometry types.

COB File Conversion

Autoconverter and Automesher Application support importing COB files (TrueSpace format) and converting them to other 3D formats like STEP, SAT, FBX, SKP, and OBJ. The conversion preserves key elements including materials, textures, and UV coordinates from the original COB file. This is made possible through our use of the Open Asset Import Library, which ensures reliable cross-platform conversions. Note that only import is supported - you cannot export back to COB format.

U3D Universal 3D Model Exchange - U3D File Format

The Universal 3D (U3D) format is an open, royalty-free 3D file standard designed for efficient sharing of 3D models across different platforms and applications. Originally developed by the 3D Industry Forum and now standardized by ECMA International (ECMA-363), U3D files offer compressed storage of 3D triangular meshes, along with attributes like color, transparency, and texture mapping. U3D is widely known for enabling interactive 3D graphics directly within PDF documents.

Main Features of U3D Files

  • Open and Royalty-Free: Maintained as an international standard, ensuring no licensing fees for developers and users.
  • 3D PDF Support: Integrates seamlessly with PDF files (ISO 32000 standard), allowing users to embed, view, and interact with 3D models inside Adobe Acrobat Reader and other compatible viewers.
  • Efficient Compression: Stores 3D geometry and properties in a compact, binary format optimized for fast transmission and document embedding.
  • Cross-Platform Compatibility: Enables 3D model viewing across Windows, macOS, and Linux without requiring proprietary software.

Convert U3D Files to Other 3D Formats

Easily convert U3D models to popular 3D formats with our Autoconverter and Automesher Application. Powered by Intel's open-source IFX library, our solutions allow high-fidelity two-way conversion between U3D and formats like STL, OBJ, SKP (SketchUp), DAE (Collada), STEP, and X3D. Preserve your 3D data integrity and optimize for CAD, 3D printing, web visualization, or digital archiving.
