Point Tool

The Point Tool is designed for precise annotation of objects that require marking specific points. It is particularly useful for tasks that involve identifying key points or structural elements of an object, such as joints, corners, or other critical features. This tool is frequently used in projects related to keypoint detection or when marking control points on images.
