Gilles commented on GEOMETRY-23:
--------------------------------
If I take this statement
{quote}I picture the representation of an n-dimensional vector as an n-tuple as
a matter of definition and not implementation.
{quote}
as meaning that "Commons Geometry" represents the "vector" concept by a data
structure that stores Cartesian coordinates, then the alternative to having
{{ofCartesian}} is to rename {{Vector3D}} to {{CartesianVector3D}}.
I.e. the equivalent of
{code:java}
Vector3D v = Vector3D.ofCartesian(1, 2, 3);
{code}
is
{code:java}
CartesianVector3D v = CartesianVector3D.of(1, 2, 3);
{code}
This has the big advantage to completely remove the ambiguity on what is being
represented (one-to-one mapping between math and code), {{of}} becomes
self-documenting and {{CartesianVector3D}} can be a
["ValJO"|https://blog.joda.org/2014/03/valjos-value-java-objects.html].
> Remove Euclidean Point Classes

> 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.
