Re: [Gnoga-list] CAE development, plotting etc.

[LOS Stéphane]

Hello,

Someone said that there are plenty of JS plotting libraries. May I 
suggest this reading :

http://www.sitepoint.com/15-best-javascript-charting-libraries/

I like this one :

And output SVG. I think I have an example in that tar ball of it.

another option would be to use the SVG backend (or any other image

Would it make sense to make Gnoga support PLplot directly as an output device? 
The first paragraph here is interesting.

I did it for Turbo Pascal, and didn't take anything like 500 hrs. I then did it
again for a specific graphics board using Meridian Ada under DOS, again in much
less than 500 hrs, and ported that easily to a different graphics board using
Janus/Ada. Certainly not all the bells and whistles, but basic 2D plotting with
Y increasing upwards and real coordinate values with user-defined ranges for the
axes.

[Gnoga-list] CAE development, plotting etc.

[Sundelin Henri]

Hello folks!

I’ve been slowly making a new CAE software in marine engineering, using Ada as 
preferred development language. As many of you know, Ada has the best 
capabilities in any compiled language to do math equations, matrix algebra etc 
– as long as you do your abstractions right.

My next big hurdle is to start on the UX, and up to date I’ve been mostly 
investigated Qt and PLPlot. Getting good scientific 2D plots is a hard 
requirement, getting some nice 3D stuff would be a nice addition.

So the big question is that is there anything suitable in Gnoga world to do 
such things? I do love the idea behind Gnoga,  it might even enable me to 
deliver the tools I’m developing as web based service, which would be a 
beautiful way to keep everything up date.

Cheers,

//Henri
Happy New Year 2016!

[Rabbi David Botton]

The simple answer is if there exists a JavaScript library in the universe
that meets your needs it can easily be bound and added. There are a number
I believe.

Re: [Gnoga-list] CAE development, plotting etc.

[Sundelin Henri]

Thanks,

I guess this means I’m going to do some testing..:)

However, if there are anyone else in this list interested in Technical 
Plotting, let me know. Maybe we could do something nice there.

Gnoga.Gui.Element.Canvas.Context_2D has what's needed for 2D drawing, so it
should be fairly straightforward to build a "native" Gnoga technical plotting
library on top of it.

Frankly,

“OpenGL has all the stuff needed for 3D, so..”

No, it is not straightforward, unless you think using 500hrs of work 
“straightforward".
PLPlot does quite fancy stuff, in very nice API.

I don’t want to start from scratch really, this stuff has done before in other 
solutions. Maybe there is something better out there?
