Matt Juntunen commented on GEOMETRY-94:
---------------------------------------
[~erans], I just had a thought that might help users navigate the API without
the need to put everything in a single namespace class: what if we created a
single convenience class per "primary" object (eg, line, plane, etc), that
contained aliases for all of the factory methods for creating subsets of that
type? We would have, for example, a {{LineSubsets}} class with methods
{{rayFromPointAndDirection()}} and {{segmentFromPoints()}}. Usage would then
look like this:
{code:java}
Line line = Line.fromPoints(a, b, precision); // still uses primary hyperplane
class for instantiation
Ray ray = LineSubsets.rayFromPointAndDirection(pt, dir, precision);
Segment seg = LineSubsets.segmentFromPoints(p0, p1, precision);
{code}
We would have {{LineSubsets3D}} and {{PlaneSubsets}} in Euclidean 3D.
WDYT?

> Project: Apache Commons Geometry
> Issue Type: New Feature
> Reporter: Matt Juntunen
> Priority: Major
> Labels: beta1
>
> There should be specific subclasses of {{ConvexSubPlane}} to allow for
> optimization and ease of use.
> - {{OpenConvexSubPlane}} - extends {{ConvexSubPlane}}; represents a convex
> subplane that is open on a least one side and has infinite size
> - {{ClosedConvexSubPlane}} - extends {{ConvexSubPlane}}; represents a convex
> subplane with finite size; the 2D subspace is a polygon
> - {{Triangle3D}} - extends {{ClosedConvexSubPlane}}; represents a triangle
> in 3D space; most 3D models are or can easily be represented with triangles
> so it would be good to have a dedicated class for this.
