Nils,
No JZY is not one of the ones we have plugged into the 3D API before (under createSurfaceTrace(...) for instance). As well as the in house developed stuff,
I have tried swapping for freehep and GL from the fable project.
The JZY API looks ok to use and I might swap the 3D renderer to JZY to see if it is better than our in-house jreality code – thanks for the suggestion!
I wonder if everyone should consider a standardized pluggable plotting API? This would mean we could agree an interface but choose plotting implementation and
in so doing disconnect algorithms from dependencies on a specific plotter – just a thought!

Subject: Re: [science-iwg] Brief update on science-iwg related discussion at EclipseCon
We spoke about swt-xy-graph being the focus at a BOF last year, I think there was a similar conclusion. It would be productive to share on this API - great idea!
We could contribute an extension API which is open source and EPL licensed (some parts are Apache).
It extends swt-xy-graph to 2D and also with a 3D capability (using jreality/JOGL), although the 3D is obviously not swt-xy-graph. The entry point for the whole API is an eclipse like design
here:
IPlottingSystem.java with
ITraceSystem.java being the interface for plotting 3D things like surfaces as well as 1D and 2D things using draw2D.
The 3D plotting is surfaces and points and stacked 1D plots. There is activity at the moment developing an iso-surface plotter, it is in the design stage only however. The video 4 here
shows the 3D surface stuff:
http://www.dawnsci.org/tools/data-handling. I will add an iso-surface video later this year.
as to plotting in 3D, have you considered
http://www.jzy3d.org/?
It is also based on jogl and has swt bindings, all licensed under BSD.
Cheers,
Nils
I like the idea of the scientific community to start sharing code via the Eclipse repository. The swt-xy-graph sounds like an excellent starting point as plotting is the most common activity
of all scientific applications. I would vote for this if Xihui and ORNL agree of course.
I suggest you add your product to the (growing) list of scientific applications based on Eclipse:
BTW SIMA and in general the work on wind turbines by Marintek looks very interesting. This is the first time I have heard about it.
I agree it would be great to have a session dedicated to scientific applications at the future EclipseCons.

we will also need his help to establish provenance and get through a CQ[1] along with any tidy-up required. I don't know how this is normally done so I've added
emo@xxxxxxxxxxx (Wayne Beaton) to the CC. Anyway, as I'm already an Eclipse committer I'll help out in any way I can.

would still have to be through the CQ process for it to be used. I consider this the less desirable option.
> I also would like to add that it was great discussing these things. We should definitely continue at the next opportunity. Meanwhile the SIMA team will probably start working on a talk
about marine operations, simulations, modeling, 3D and so forth ;-) And it would be great if we also get other talks from the Science IWG community. If we cannot get these into the official program we could still do shorter versions at one or more BoFs. I
would certainly love to see what you all are up to.
