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)
SVF
SVF Strengths
- Acted as a crucial pioneering stepping-stone in proving that scalable, zoomable vector graphics were viable and necessary for the World Wide Web
Limitations
- Completely obsolete and unsupported by modern web standards
- Required end-users to install bulky, proprietary browser plugins
- Causes significant developer confusion today due to Autodesk adopting the exact same acronym and file extension for a completely different technology
