Technical note

How U3D and GIF differ in practice

GIF has a palette of at most 256 colours, and a shaded render of a curved surface uses far more, so smooth gradients show visible bands. For a turning preview, Create multiple frames in the 3D formats loading settings renders the model at a series of angles into one animated GIF. Every frame is a full image, so the file grows with the frame count and the picture size: a short turn at a modest size is usually enough for a product page. U3D 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 GIF 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 U3D files. reaConverter renders each model to GIF at the angle you set, a whole folder at a time.

  • Turn the model between two angles over several frames to get an animated spin
  • Script the job from the command line for pipelines and scheduled runs
  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Pick up new models automatically with Watch Folders
