This project is a newly proposed user interface for point cloud editing. As the above picture shows, users can edit a point cloud via a sketch-based interface. Users can add new points and erase unnecessary points.

First, users sketch the boundary of missing areas of a point cloud. The system then automatically detects the depth of the user assumed and then smoothly interpolates the selected missing areas by adding new points to the point cloud.

This tool is similar to the Sketch Tool. First, users sketch the boundary of unnecessary areas of a point cloud and then the system erases the points inside the sketch.
