# Annotation Tool

3D Multi-Sensor Fusion Tool allows labelling of point clouds. The Tool Supports multiple features and interactions to support precise labelling. View [key features](/annotation-tool/key-features.md).

## Tool Support

* Datasets of Multiple sensors: Images, LiDAR, RaDar
* Sensor fusion: Labelling across sensors simultaneously
* Feature to Label Sequential & Non-Sequential Datasets
* Multiple [Drawing Tools](/annotation-tool/drawing-tools.md) to label points in 3D & 2D datasets:
  * [Cuboid](/annotation-tool/drawing-tools/cuboid.md), [Polygon 3D](/annotation-tool/drawing-tools/polygon-3d.md), [Brush Sphere](/annotation-tool/drawing-tools/brush-sphere.md), [3D Polyline](/annotation-tool/drawing-tools/polyline-3d.md), [Polygon 2D](/annotation-tool/drawing-tools/polygon-2d.md), [Rectangle](/annotation-tool/drawing-tools/rectangle.md), [Polyline 2D](/annotation-tool/drawing-tools/polyline-2d.md), Rectangle with Keypoint
* Aggregation of point clouds for identifying and marking Stationary Objects.
* Interpolation to mark Moving Objects
