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)
JPEG-XS-(HEIF)
JPEG-XS-(HEIF) Strengths
- Provides sub-millisecond encoding and decoding latency while retaining visually lossless quality
- Brings the extensive metadata, EXIF, XMP, and color-profiling capabilities of the HEIF container to JPEG XS
- Allows grouping of multiple high-quality JPEG XS frames into a single collection file
Limitations
- Zero web browser compatibility, limiting it entirely to professional and industrial hardware workflows
- Extremely niche adoption compared to standard HEVC-based HEIC or raw JPEG XS codestreams
- Requires custom parsing logic to extract the JPEG XS codestream from the HEIF boxes
