This is a real-time video processing application for the Raspbery Pi.
It opens the Raspi camera and pass it through a fragment shader. All the shader's uniform variables are automatically exposed via OSC.
This repo is intended to be cloned in the /opt/vc/src/hello_pi folder present on Raspbian distribution.
You should follow the /opt/vc/src/hello_pi/README first.
Then you need to install the liblo library :
sudo apt-get install liblo-dev
And then run make
Modify the frag.glsl shader just as you like. But remember that the Raspberry Pi GPU driver is not fully compliant with OpenGL. For example, I found no way to intialize uniform variables. Moreover, the GLSL compiler is quite sensitive, and may fail because of a typo or removing the last 2 empty lines... All compilation errors are reported to console.
