Subject [jira] [Commented] (MATH-1437) Add/extend unit tests for o.a.c.m.geometry.partitioning and related packages

Matt Juntunen commented on MATH-1437:
-------------------------------------

Thanks! I am planning on adding some more updates. Here's what I have in mind so far (time-willing):
 # Finish adding unit tests for the other packages mentioned in this issue in order to flush
out any remaining bugs (I know there are at least a couple left) and provide a good base for
refactoring later on.
 # Create a separate commons-geometry project like you have mentioned earlier.
 # Update/clean up the API to make it easier to use. It's kind of a beast right now. One of
the biggest things I'd like to change is all of the type casts necessary in order to perform
any kind of meaningful operation. There are general interfaces for all of the types, but in
many places the code has to assume a particular concrete implementation and cast to it in
order to do useful work.
 # Look into improving performance, especially for bsp tree creation from boundaries. Right
now, the code  takes over a minute to create a PolyhedronsSet for the utah teapot (~1500
facets). Other libraries I've used could do approximately the same thing in a few milliseconds.
Admittedly, these other libraries don't have the features that commons-math does, but still,
a minute is way too long here.

I would like to add classes for reading and writing geometry data from other file formats
but I think the core functionality needs polishing first.

> Additional unit tests should be added for the following packages:
>  * o.a.c.m.geometry.partitioning
>  * o.a.c.m.geometry.euclidean.oned
>  * o.a.c.m.geometry.euclidean.twod
>  * o.a.c.m.geometry.euclidean.threed
> The current tests provide adequate code coverage but don't seem to thoroughly exercise
the code base and check edge cases.
