Toon3D: Seeing Cartoons from a New Perspective

Toon3D lifts hand-drawn images to 3D with a piecewise-rigid deformation optimization at hand-labeled keypoints and using monocular depth as a prior. The project page is at https://toon3d.studio/ and the Toon3D Labeler is at https://labeler.toon3d.studio/. Follow the steps below to run Toon3D!
  1. Prepare and Process Data
    • Upload images and click on "Process Data" to generate processed data.
    • Download the processed data.
  2. Label Data
    • Upload the processed data and label points using the labeler ("Upload ZIP").
    • Click export and upload the points.json to the "Labeled Points" section.
  1. Generate 3D Output
    • Click on "Run Toon3D" to run the structure from motion pipeline.
    • Download the output and inspect locally (point cloud, mesh, Nerfstudio dataset).
  2. View in Web!
    • Click on "Open Viewer" to view the output in an interactive viewer powered by Viser.
    • Reach out if you have any questions!
