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)
J2C
J2C Strengths
- Provides state-of-the-art wavelet compression for high-end professional workflows (Digital Cinema)
- Allows for highly efficient progressive decoding (by resolution or quality layer) natively within the stream
- Supports lossless mathematical compression and high bit-depths (up to 16-bit per channel) natively
Limitations
- Lacks a standard container to store color space info or metadata, requiring external systems (like MXF or DICOM) to map colors correctly
- Extremely computationally expensive to encode and decode compared to standard DCT-based JPEG
- Zero web browser support
