Would you do a
presentation at the
show and tell?
So I had a bit of a think …

And suggested …
openFrameworks
It’s something many of us are interested in
Something we should be aware of
Let’s see what we can do in 10 days
10 days of openFrameworks
4 days ago …
How’s your
presentation
coming along?
Really good!

I have a new title for it though …
4 days of Openframeworks!
Day 1
• What is openFrameworks
• How do I get started
openFrameworks is an open source
toolkit designed for “creative coding”
Combines complex areas of computing
into a “minimal and easy to grasp api”
Graphics
Image Processing
Sound Processing
Computer Vision
Arduino
Client Server
Lots more …
Very Active Community
689 +
non-core addons
What can I do with it?
Interactive Movies
Control Hardware
Computer Vision
Projection Mapping
Getting Started
Things you need to know
Cross Platform
• Windows

• Mac OSX
• Linux
• iOS
• Android
Most code examples are xCode projects.
Mac is platform of choice.
C++
http://www.openframeworks.cc/

4.

Download the version for your platform.
Unzip it
Put is where you prefer e.g. C:ProjectsOpenframeworks
Build and run the examples
Setup …
Update …

4 days of openframeworks

Editor's Notes

  1. The big power behind open frameworks is the very active and generous community.
  2. Growing really fast
  3. Used to control the LED lights in this installation
  4. This took me about an hour to get up and running with the examples.First installed on windows and ran with Visual Studio. Easier to install on windowsThen tried on Mac – Some build issues but soon got past these with a bit of Googling
  5. An open frameworks application class has three main methodsSetup..Setup all the bits you need Update..Calculate your state. This is where your main processing happens.Draw ..Draw your state
