=============
Visualizer made in C and OpenGL with SDL2.
About
-----
I wrote this visualizer specifically for a song I made called Undercurrents.

Compile
-------
Make sure `sdl2` is installed. Run `make` to compile the program:
$ make
cc -o src/ryb2rgb.o -c `sdl2-config --libs --cflags` -lGL -lm -Wall -Werror -O2 src/ryb2rgb.c
cc -o src/particle.o -c `sdl2-config --libs --cflags` -lGL -lm -Wall -Werror -O2 src/particle.c
cc -o undercurrents `sdl2-config --libs --cflags` -lGL -lm -Wall -Werror -O2 src/undercurrents.c src/ryb2rgb.o src/particle.o
$ ./undercurrents
...
fps=11.627907 ringCount=0 particleCount=0 recycledParticles=0
fps=66.666667 ringCount=2 particleCount=6 recycledParticles=0
fps=66.666667 ringCount=4 particleCount=20 recycledParticles=0
...
Usage
-----
```
$ ./undercurrents -h
Usage: undercurrents [-h] [--longOpt var]
Options
-h, --help print this message and exit
-p, --paused start in the 'paused' state
--configVariableName value set a configuration variable, see below
configuration variables can be passed as long-opts
ie: undcurrents --windowHeight 500 --windowWidth 700 --ringsMaximum 20
Configuration
windowWidth=1200
windowHeight=1200
particleSpeedMaximum=30
particleSpeedFactor=100
particleRadiusMinimum=1
particleRadiusMaximum=5
particleHeightMinimum=0
particleHeightMaximum=5
particleLineDistanceMinimum=0
particleLineDistanceMaximum=200
particleLineRingDisable=-1
particleExpandRate=20
particleBornTimerMaximum=1000
particleColorSpeed=50
ringsMaximum=35
alphaBackground=7
alphaElements=25
timerPrintStatusLine=2000
timerAddNewRing=1000
Controls
- press up / down to modify particle speed
- press left / right to modify particle line distance factor
- press 'b' to toggle blank mode
- press 'f' to toggle fading mode
- press 'l' to toggle particle lines mode
- press 'm' to toggle color modes
