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)
PaintShop-Pro-PSP

PaintShop-Pro-PSP Strengths

  • Provides robust, non-destructive editing capabilities with full support for vector layers, adjustment layers, and layer blend modes
  • Historically offered a highly capable and affordable alternative to Adobe Photoshop's PSD format for Windows users
  • Features proprietary support for 'Picture Tubes' (.tub), a unique brush technology that paints sequential or random raster objects along a path
Limitations
  • Deeply proprietary format tied exclusively to the Corel/Alludo ecosystem
  • Third-party software support (like GIMP or ImageMagick) is often limited to parsing older .psp files, frequently failing to render complex layers in modern .pspimage files
  • No support in modern web browsers; must be exported to a flattened web format (JPEG/PNG) for online viewing

When to choose which format
