Hello,

this is a beginners work - one of the first sketches I made during an education-project. I thougt I shared the fruits of my labors with you.

The goal was to create a pattern-generator at any kind. Mine creates a radial pattern based on the time when you start the sketch up. When done it shows so with a green checkmark - if you like the pattern you can leftclick the screen and it will be stored as a screenshot and a CNC-file which can be used to mill the pattern. Size and depth need to be changed at the beginning of the code.

Have fun!

ControlP5: using text in accordion

Hello again,

id like to display values in my accordion-dropdowns but cant find a proper way to implement i.e. a "textlabel".
Could someone give me a hint how Id do this? sojamo.com isnt really easy to get into for newbies like me.

Edit: Ive also been wondering if I can edit the way the text of bangbuttons is being displayed can be edited. Id like it to appear right and left of some buttons, if possible. :)

Creating instances from a class with a for-loop

Hello,

im still quite new to processing && programming in general, so bear with me if this is actually an obvious thing to you :)

What im trying to get is a circle divided in a certain number of segments. The number of segments can be controlled via the keyboard (Later ControlP5).

I already wrote a class creating a segment. Right now I made it so the Constructor asks for the center of the circle (which is width/2, height/2) and the "void display" is fed with the angles of the starting-anchorpoint, the ending-anchorpoint and the radius of course.

The Sketch works without giving out an error, but it doesnt show anything.

What am I doing wrong?

Edit: The Code its all about:
3. Kreissegment meinSegment;
5. int segmentzahl = 4;
6. int segmentmaximum = 12;

Developing Apps for Win 8 with Processing?

Hey,

ive been working and learning with Processing for a few weeks now, mind you - im completely new on the topic of programming, so this might be silly to ask: Can I create simple apps for the Windows 8 MetroUI with Processing?

Im spending quite some time in the Metroscreen and even though ive searched the Appstore up and down I found no Clock-app to place as a live-tile. They were all either un-handy ore rather ugly to look on.

Greetings.
