Ground and Ceiling Mover
The Ground and Ceiling Mover is a two-way slider on the bottom right of the point cloud that allows users to hide points from ceiling to ground and vice-versa while labeling an object.
Ground and Ceiling sliders help filter out points which the user does not need to view.
Benefits
Enhanced Focus: Allows annotators to concentrate on a specific area of interest, eliminating distractions from irrelevant regions.
Increased Annotation Accuracy: Provides a clearer view of smaller, detailed areas, aiding precise annotation.
Steps to use Ground and Ceiling Slider
