Matt Juntunen commented on GEOMETRY-23:
---------------------------------------
Both names are correct: we're describing a vector that is represented using
Cartesian coordinates. However, the name "vector" is far more useful since it
describes what it represents geometrically and the operations that it supports.
I refer you to my prior confusion when I first saw the class name
"Cartesian3D": "Can I normalize this?", "Will this work to get a dot product?",
"How do I get a vector from this?".

> Key: GEOMETRY-23
> URL: https://issues.apache.org/jira/browse/GEOMETRY-23
> Project: Apache Commons Geometry
> Issue Type: Improvement
> Reporter: Matt Juntunen
> Priority: Major
> Labels: pull-request-available
>
> Based on discussion of the current Point/Vector API in GEOMETRY-14 and
> research into other geometric libraries, I think we should remove the
> Euclidean Point?D classes and make Vector?D also implement Point. This will
> end up being similar to the previous commons-math design but avoids the issue
> raised in MATH-1284 since the Point and Vector interfaces are not related.
> They just happen to be implemented by the same class, which we're calling
> Vector?D since a vector can be used to indicate a point (by adding it to the
> origin).
> In the course of trying this out this design, I ended up removing 7 classes
> and simplifying several methods. I think that's a good indicator that this is
> a good design choice.
