Some time ago, I mentionned the possibility to develop a plotting backend for octave, written in Java, using the Java/Octave integration package available in octave-forge. These last few days, I gave it a try, by taking the Graphics package from JMathLib (which I improved quite a lot) and building a simple octave layer on top of it. I could then quickly get something that is already pretty usable. You can see a demo screenshot in attachment.
Now, I'm facing a few issues: 1) I do it mainly for fun and for my personal use; if I want to make it more complete and robust, I'd probably need some help; so if anybody is interested, please standup 2) the octave layer I wrote doesn't re-use code from octave's current plot package, but it could probably do it; the problem is that it's not obvious where's the separation line between generic code and backend-specific code; is it possible to make this separation clearer, for
instance by using separate directories? This would clearly exposes the functions that need to be overloaded.
My current code is not "handle-based" yet, because I focused on the Java implementation. Turning it into handle-based graphics shouldn't be difficult because of the OO-nature of Java (and the implementation). The current features are: - 2D/3D plots (3D are only "transparent" meshes, it's not full 3D surfaces) - markers and line styles like in Matlab - basic text layout (with subscript and superscript) - subplot support - printing support
There are still lot of bugs and missing features; that's why I'm asking
for some help. If people is interested in this package, I might post the
code somewhere.
