3D Workflow

From picture to 3D model

Need a 3D GLB from a flat FITS image? reaConverter vectorizes it, extrudes the shapes to the height you set, and works through a whole folder at once.

  • Each image is vectorized first, then extruded to the height you set in millimetres
  • Works best with logos, signs and line art: a photo has no clean outlines to follow
  • Tune the tracing precision so the edges follow the original
