---------------------------------
Resolution: Done

> Key: GEOMETRY-34
> URL: https://issues.apache.org/jira/browse/GEOMETRY-34
> Project: Apache Commons Geometry
> Issue Type: Improvement
> Reporter: Matt Juntunen
> Priority: Major
>
> There are currently only generic implementations of the {{SubHyperplane}}
> interface for each dimension. These implementations use the {{(n-1)}}
> dimension {{Region}} class in order to implement the {{SubHyperplane}}
> methods. This means that each operation on a {{SubHyperplane}} of dimension
> {{n}} involves operations on {{Region}} instances of each {{k<n}} dimension.
> This is incredibly inefficient. In many situations, most of the methods of
> the {{SubHyperplane}} interface can be implemented directly in the {{n}}
> dimension. Optimized subclasses should be created for each of these
> situations.
