This Sunday, May 23rd there will be an OpenFrameworks beginners workshop at SETUP in Utrecht (the new media lab at Neude). The workshop is a collaboration between OpenToko, OF Freakdays and Setup Utrecht.

OpenFrameworks is a free application framework designed for creative coding. It’s a c++ library designed to assist the creative process by providing a simple and intuitive framework for experimentation.

OpenFrameworks is designed to work as a general purpose glue, and wraps together several commonly used libraries under a tidy interface: openGL for graphics, rtAudio for audio input and output, freeType for fonts, freeImage for image input and output, quicktime for video playing and sequence grabbing.

The code is written to be both cross platform (PC, Mac, Linux, iPhone) and cross compiler. The API is designed to be minimal and easy to grasp. There are very few classes, and inside of those classes, there are very few functions.

The day starts at 10.00h with a ‘Introduction to OpenFrameworks’ lecture by Rick Companje followed by a talk by Diederick Huijbers showing the work he created at the OFLab in Breda at the Graphic Design Museum. The afternoon will be “hands-on” where everyone (beginners and experienced users, in groups or alone) can work on their own OpenFrameworks projects. Several experienced OpenFrameworks users will be there to help out.

Topics being adressed during the talks:

- What is OpenFrameworks and how to use it?
- Understanding the code examples and how to modify them for your own needs.
- How to use OpenFrameworks for text, audio, vector graphics, 3D graphics, vector math, images, movies, live video, xml files, hardware (ie. Arduino), network (ie. Open Sound Control), hi-res PDF or Illustrator output etc.
- We will teach you how to build a simple Particle System and also how to create some nice graphic design effects for creating printable posters.

Please bring a laptop with Mac OSX, Windows or Linux and download XCode (mac) or CodeBlocks (windows, linux) and download the OpenFrameworks version 0.061.

There will be coffee, tea and cookies and we will arrange a basic lunch. There is no fixed entrance fee but instead we ask you for a donation for what the knowlegde you gained is worth to you helping us to cover our expenses.

There is a maximum of 25 participants so please register now if you want to join.

Location: SETUP Utrecht, the old ABN-AMRO building at Neude 4, Utrecht
Date/time: May 23rd 2010 – 10.00h – 17.00h

on May 2nd, Toko will be about Open Frameworks 6. Open Frameworks is a free application framework designed for “creative coding”. OpenFrameworks is written in C++ and runs on Windows, Mac OS X, Linux and iPhone. For more information and examples, go to http://www.openframeworks.cc. The day starts at 10.00h with a lecture by Rick Companje and possibly Theo Watson.

Topics that will be addressed are:
-getting started
-what’s new in Open Frameworks 6
-what is and isn’t Open Frameworks good at (yet)
-what can we do to improve OF

From 16.00h to 23.59h will be a working session. What you could do there is:
-start on a project and get some help
-get a project made in OF5 to work in OF6
-help improve OF
Send us an email if you have any request for any OF topics you would like us to deal with.

Toko is an initiative of Rick Companje, Diana Wildschut and Harmen Zijp. We are not a funded organisation. Toko is set up as a knowledge sharing community. We open our workshop to people who are interested in participating. Everybody is welcome and everybody should share the knowledge they have. Which doesn’t mean you have to know a lot to join. We ask you to make a donation for the food we cook and for what the knowledge you have gained from the workshop is worth to you. We also ask you to give us some topics about which you know something, so that next time you might be able to teach (part of) a Toko.

====== Demonstratie OpenFrameworks door Rick ======
virtueel mapje libs, met openframeworks spul.

void main() opent new window. Glut is window manager. voor iphone is andere.

F11 switch tussen CPP en headerfile
void setup: initialisatie

programma is eeuwige loop update -> draw

update: berekeningen
draw: tekenen (video)

framerate -> niet default gezet.

documentatie is achterhaald v. 0.03 oktober 2007 laatst ge-update
gaat boek over v. 0.06 komen

wiki.openframeworks.cc

waarom werkt openframeworks minder snel dan processing?
steilere leercurve, langer opzetten project, niet 1 play knop?
veel overhead -> dependencies?

Wat is het verschil tussen compileren en linken?

addon example
addon = plugin op openframeworks

tip, hou mapstructuur aan en copy-paste. Alle paden zijn relatief. Er lijkt jammergenoeg niet echt een betere optie…

codeblox project file bevat alle paden.. is xml, dus is wel te editen.

neem allAdonsExample -> zo dik mogelijk.. meest aangekleed.

vanuit emtpy project-> include cpp files. voor release en debug editie
