Technical note

What changes when you convert FBX to FITS

A 3D model has no front of its own, so the FITS shows it from one viewpoint: the angles you set on the X, Y and Z axes, or a preset such as the isometric view. Whatever faces away from that viewpoint is not in the picture, so a part with features on several sides needs several images, which the multiple-frames option renders in one run. FBX describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the FITS afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not FBX files. reaConverter renders each model to FITS at the angle you set, a whole folder at a time.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Render a turning model as an animated GIF when one still image is not enough
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Use one angle and size for every model, so a catalogue looks consistent

FAQ

FBX to FITS Conversion

What are FBX files?

The FBX vector format was initially associated with Filmbox and created as a version of the FLM format, offering more interoperability. Filmbox was a predecessor of Autodesk's MotionBuilder, created for motion capture devices by Canadian developer Kaydara, later acquired by Alias. Starting with 2006, FBX became a proprietary format of Autodesk. FBX is currently part of a set of tools known as Autodesk Gameware, used by designers in developing games and supporting character animation, AI and advanced user interfaces.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
