Programming Interactivity

2nd Edition Imminent

admin — Mon, 09 Jan 2012 17:45:49 +0000

I’ve done a terrible job updating this blog, but no more! The 2nd edition, updated for OF007, Arduino 1.0, and Processing 1.5 is coming out any day now I’ll have full code downloads this time, nice drawings done with Fritzing, well commented examples, and there’s about 90% fewer typos and errors in this one. As soon as it’s out I’ll post info here!

Programming Interactivity and OF 007

admin — Tue, 18 Jan 2011 09:15:22 +0000

So, there’s a new release of OpenFrameworks pending, 007, as well as significant updates to Arduino and Processing since the book was published (almost) 2 years ago, and that’s an excellent reason to update a lot of things in Programming Interactivity. I’m in discussions with O’Reilly about this and I’ll be getting some news up here ASAP.

O’Reilly offering Processing+Arduino training

I figured I had to mention this: http://training.oreilly.com/arduino/. It’s a pretty big deal (well, I think so anyways).

Also, for anyone interested in data visualization, the London Data store is releasing scads, gobs, mounds, piles, of data free for anyone to use: check here for more info http://twitter.com/londondatastore

Useful and interesting. More here

Just wanted to put this up in case anyone was interested in exploring these further: the site is falstad.com and is a great resource for anyone interested in learning more about components, circuit design, the laws of electricity, or just messing about.

Though you can always just stop by and say hello, I may be rather bored :) More info on where the booth is here

OpenGL in Processing using Eclipse

You want to do it. It’s going to make your life easier, especially if you’re doing something big. There are steps up on the Processing site but I think these courtesy of the processing forum user ‘letsgooutside’, are much easier. Here are the steps to follow:

1. Make a new Java project
2. Add a new folder to the project root named “lib” or “X” or whatever
3. Add a new folder inside of “lib” called “natives” or again, whatever
4. Right-click on your “lib” folder and choose “Import”.
5. Browse to your “Processing\lib” folder and import the following file so that your application has access to

– core.jar

6. Right-click on your “lib” folder and choose “Import”.
7. Browse to your “Processing\libraries\opengl\library” folder and import the following files:

– gluegen-rt.jar
– jogl.jar
– opengl.jar

8. Right-click on your “natives” (which is inside your “lib” folder) and choose “Import”.
9. Browse to your “Processing\libraries\opengl\library” folder and import *ALL* files, *EXCEPT* the following:

– gluegen-rt.jar
– jogl.jar
– opengl.jar

10. WINDOWS: In your project’s “lib” folder, right-click “gluegen-rt.jar” and choose “Properties”.
OSX: At your project root select “Build Path” and then “Configure Build Path”. Select gluegen-rt.
11. Under “Native Library”, click “Workspace” and browse to “YourProjectName/lib/opengl-natives” and click “OK”.
12. WINDOWS: In your project’s “lib” folder, right-click “jogl.jar” and choose “Properties”.
OSX: At your project root select “Build Path” and then “Configure Build Path”. Select “jogl.jar”.
13. Under “Native Library”, click “Workspace” and browse to “YourProjectName/lib/opengl-natives” and click “OK”.

It should look like this:

14. Run this as your main class:

import processing.core.*;

import processing.opengl.*;

import javax.media.opengl.GL;

public class Test extends PApplet

{

    public void setup()

    {

         size(800, 600, OPENGL);

    }

}

The key things to note here are that your core JAR files are *not* in the same folder as their respective natives, and that, and for Windows, the DLL files absolutely must be in with these natives.

This is amazing, definitely excited to get my hands on one of these. I’ve got ideas aplenty already.
