3DS
3DS Strengths
- Nearly universal support; practically every 3D modeling application created in the last 30 years can read and write 3DS files
- Extremely simple, well-documented binary structure that is trivial to parse for custom rendering engines
Limitations
- Hard limit of 65,536 vertices and polygons per mesh due to 16-bit addressing
- Enforces archaic 8.3 MS-DOS filename length restrictions for all linked texture files
- Lacks support for modern 3D concepts like skeletal animation (rigging), normal mapping, and physically based rendering (PBR)
EDMICS-MMR
EDMICS-MMR Strengths
- Utilized the highly efficient MMR (Group 4) algorithm, which allowed massive, E-size engineering blueprints to be compressed into tiny file sizes suitable for 1990s hard drives and networks
- Deeply integrated into Fuji Xerox hardware and database systems for seamless scan-to-archive workflows
Limitations
- Completely proprietary and closed-source, making modern archival extraction and migration extremely difficult
- No support in modern image processing libraries like ImageMagick, libvips, or standard TIFF viewers without first stripping the proprietary header
- Strictly limited to 1-bit monochrome images
