3D Workflow

From 3D model to picture

Turn Q3D models into SGI 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
  • Draw isometric, top, front or side views as line drawings with 2D projection
  • Pick up new models automatically with Watch Folders
  • Render a turning model as an animated GIF when one still image is not enough
