| Interface | Description | 
|---|---|
| FullProjection | Full vector space projections. | 
| Projection | Base interface used for projections in the ELKI visualizers. | 
| Projection1D | Interface for projections that have a specialization to only compute the first component. | 
| Projection2D | Projections that have specialized methods to only compute the first two
 dimensions of the projection. | 
| ProjectionParallel | Projection to parallel coordinates that allows reordering and inversion of
 axes. |
