Structure of code
|
|
-----------------
|
|
|
|
Main components of this project are three:
|
|
* Processing code taking care of visuals (in folder pde/)
|
|
* SuperCollider code - generative and live sound, GUI interface for touchscreen (in folder scd/)
|
|
* Renoise module - composition (sound) and midi triggers for Processing/visuals (in foder rnx/)
|
|
|
|
Helper folders:
|
|
* dat/ contains some data for SuperCollider (for now)
|
|
* smp/ contains samples for SuperCollider
|
|
* doc/ contains some simple documentation (this file!)
|
|
* dev/ is some development code (may not be in git)
|
|
* textures for Processing are in pde/IF3Si/images and may not be in git)
|
|
|
|
How is this run?
|
|
================
|
|
|
|
Hardware setup contains of a computer running a capable OpenGL card (Nvidia?) with two displays. One is a multitouch display device (1920x1080 but not necessary), the other is either a simple display monitor or a projector capable of 60fps at FullHD (1080p). Underlaying OS is Linux.
|
|
|
|
## Software
|
|
|
|
Edit `~/.processing/preferences.txt` and change `run.display=1` accordingly. I have it on 1, since 0 is my 'primary' display, which is the touchscreen. See also an example xorg.conf. I personally do the following - I access everything through a remote laptop, loging in through ssh. Processing applet is run remotely by using two small bash scripts:
|
|
|
|
*processing-runsketch.sh* (this one needs to be on the executable path):
|
|
```bash
|
|
#!/bin/bash
|
|
if [[ -z $1 ]]; then
|
|
echo "error. no argument."
|
|
echo "need the sketch path"
|
|
else
|
|
|
|
export DISPLAY=":0"
|
|
~/src/processing-2.2.1/processing-java \
|
|
--force \
|
|
--sketch=$1 \
|
|
--run \
|
|
--output=$1/output
|
|
|
|
fi
|
|
```
|
|
|
|
and
|
|
|
|
*processing-runsketch_IF3.sh*:
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
while (true)
|
|
do
|
|
# clear
|
|
processing-runsketch.sh ~/PROJECTS/IF3Si/pde/IF3Si/
|
|
echo
|
|
echo "~~~ Program has quit. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "
|
|
echo
|
|
done
|
|
|
|
```
|
|
|
|
### SuperCollider
|
|
|
|
*IF3supercollider.sh*:
|
|
```bash
|
|
#!/bin/bash
|
|
export DISPLAY=":0.0"
|
|
/usr/local/bin/sclang ~/PROJECTS/IF3Si/scd/IF3Si.scd
|
|
|
|
```
|
|
|
|
**Renoise sends MIDI to SuperCollider who controls Processing patch via OSC.**
|
|
|
|
## notes
|
|
|
|
Monitor files while developing to restart Processing sketch on save with [`entr`](http://entrproject.org/). After running the sketch in one terminal with `processing-runsketch_IF3.sh`, in another terminal run something like
|
|
```
|
|
ls PROJECTS/IF3Si/pde/IF3Si/*.pde | entr killall java
|
|
```
|
|
(this will kill other running instances of java, so beware)
