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)
DECE-Graphic
DECE-Graphic Strengths
- Allowed the UltraViolet DRM ecosystem to easily distinguish structural UI/cover graphic assets from actual encrypted video tracks in a Common File Format container
Limitations
- Completely obsolete since the 2019 shutdown of UltraViolet
- Unnecessary abstraction, as the underlying files were just standard JPEGs or PNGs
- Causes modern strict MIME-type validators to fail if they rely on the Content-Type header
