The Processing example used libraries that can be found in OF's addons, which draws the attention to the limitations of pursuing an entire translation of the examples. There's other examples that use theGeomerative example and the Generative Design library that are only available to Processing –or Java based IDEs–. Anyhow, this particular example used a PDF converter and Calendar libraries to export the application's canvas onto images with a timestamp. In the failed attempt I was able to include a calendar addon that didn't end up using in the working one.
Even though there's a Project Generator that will include whichever addon needed, it doesn't work every time. Since this was one of those times, I ended creating the failed attempt in the same folder of the ofxICalendar addon. To try and solve one of the primitive drawing elements I sought another addon called ofxVectorGraphics, that couldn't ever got it working on an already created project.
There are primitive functions in OF similar to Processing's, the arc however is not one of them. Instead, there's two ways to go around this. The addon mentioned before, and using an object called ofPath that contains the function arc. After a lot of trial and error I was able to finally get an arc drawn in an isolated project. As any OF project, you have to create the variables and objects in the *.h file and then you can work with them in the *.cpp file. What I came to know, after figuring out the specifics of not filling, outlining, setting the resolution and not closing –to an extent– arcs was, invoking the function needed to actually draw the function. This particularly was completely counter intuitive from the previous programming experience.
After Kyle McDonald's workshop in introduction to OF I learned that the project could be simplified significantly to one *.cpp file. This meant however that I wouldn't be able to include the feature of exporting an image with a timestamp. Currently this is the working translated project. I would also like to thank AV –Sehyun Kim– for helping me out on how to –again– draw the arcs.
