# Microcosmic Gazing 5
This repository is an OpenFrameworks project (of_v0.12.0_linux64gcc6_release).
It depends on the following libraries:
- ofxOpenCv
- ofxCv
- ofxGui
- ofxOsc
## Video
It will try to open a video file called `movie.mp4` that should have 1280x720 pixels.
The video file should be on `./bin/data/video.mp4`.
## Open Sound Control (OSC)
This project contains an OSC receiver and an OSC sender.
### OSC Receiver
Listening on port `12345`, this receiver will accept the following messages:
- `/cv_invert boolean`
- `/cv_area_radius_min integer`
- `/cv_area_radius_max integer`
- `/cv_threshold integer`
- `/cv_tracker_age_min integer`
- `/cv_tracker_age_max integer`
- `/cv_tracker_persistence integer`
- `/cv_tracker_distance_max integer`
- `/sender_location string`
- `/sender_port integer`
#### oscsender
Using the program `oscsender` you can change the computer vision threshold with:
```
oscsend localhost 12345 /cv_threshold i 110
```
#### PureData / PlugData
Inside the folder `puredata` there is a `.pd` file created with PlugData that controls all computer vision parameters over OSC with sliders.
### OSC Sender
There is code for two types of sender available. They both send messages to port `12346`.
#### Data Frame
Once data is acquired by computer vision, it's encoded and sent over as a single message on the address `/data_frame`.
The first argument on the message is the amount of blobs found by the contour finder.
The following values are `label`, `age`, `contourArea`, `center.x`, `center.y`, `velocity.x` and `velocity.y` for each blob found.
#### GLSL Viewer
To help creating shaders, there is also a sender that sets the uniforms with the blob positions on a glsls shader.
This is a proof of concept on how to create shaders from the blob characteristics.
On the folder `glslviewer` you can find a python script called `cheat.py` that generates a glsl fragment shader with N preallocated positions.
