A starting point for you: try out the Federgraph formula, then improve on it. Eventually the real program that implements it (fast and good looking) will come to the Pi. http://www.riggvar.de/federgraph-formula.html (* Clear *) ClearAll[x1, x2, x3] ClearAll[y1, y2, y3] ClearAll[l1, l2, l3] ClearAll[...

I ran into a bug in gles20.pas (dependency on X) for which I summited a bug report to freepascal.org.

Thanks for the update, good to know about.

Thaddy wrote:In that case I will be happy to put in some effort

Thank you, don't rush, and use the email in FrmMain.pas to contact me if you have questions or requests.

I created the open source project and will upload the Delphi version of the Example program soon. If you have an implementation for the raspberry pi it should go there, in its own folder.

Ah, the answer is yes, I own every bit of it, so far. I don’t need to ask.

If you are aware of what that means and if you are willing and *able* to comply. I meant free as in ‘not getting paid for’. GPL v 3 would be good for the example using the Federgraph formula. As I understand it, everyone who uses that code would be required to make the source of any addition or alt...

I mean free software, but everyone should be able to add stuff and sell it. The Federgraph application is written in Delphi XE4, it is a Firemonkey HD project. I have filed a bug report in Embarcadero’s QC (Quality central) system with an example project attached, it is downloadable. I can do a slig...

hm... just for fun? I need a good basic example otherwise I cannot contribute stuff for free. If you want something in return for you effort, than help me with Federgraph for Windows 8 RT. Note that I (and other users, including very young ones) need help only with the 3D system stuff, so that we c...

Is anyone interested in using the Federgraph formula as a 3D model to make a 3D example program that runs on the Pi? http://www.riggvar.de/federgraph-formula.html Something similar to ‘3D Parametric Function Plotting’, but using the Federgraph model as the function to plot. I would like ‘Developing ...
