Technical note

What changes when you convert GLB to ICO

A 3D model has no front of its own, so the ICO 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. GLB 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 ICO afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

3D Workflow

From 3D model to picture

Turn GLB models into ICO previews without opening a 3D program. Set the angle once, and every model in the folder is rendered the same way.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Pick up new models automatically with Watch Folders
  • Render a turning model as an animated GIF when one still image is not enough
