LJ OSC and Websockets laser commands
v0.7.0


LICENCE : CC
by Sam Neurohack, Loloster, 
from /team/laser

Commands reference. Use commands from websocket (webUI) or OSC, do not set values in redis directly except for /pl.

/scale/X/lasernumber value   
/scale/Y/lasernumber value

/client or note on < 8 : change client displayed for Current Laser
23 < /noteon < 32 : PL number displayed on webUI simulator    

/grid/lasernumber value (0 or 1) : switch given laser with grid display on or off

/black/lasernumber value (0 or 1) : set given laser to black on or off

/ip/lasernumber value : change given laser IP i.e '192.168.1.1'

/kpps/lasernumber value
Live change of kpps is not implemented in newdac.py. Change will effect next startup.

/angle/lasernumber value : increase/decrease angle correction for given laser by value

/intens/lasernumber value : increase/decrease intensity for given laser by value 

/resampler/lasernumber lsteps : change resampling strategy (glitch art) for given laser
lsteps is a string like "[ (1.0, 8),(0.25, 3), (0.75, 3), (1.0, 10)]"
 
/mouse/lasernumber value (0 or 1) 

/swap/X/lasernumber value (0 or 1) 
/swap/Y/lasernumber value (0 or 1) 

/loffset/X/lasernumber value : change X offset  of given laser by value
/loffset/Y/lasernumber value : change Y offset of given laser by value

/order value : instruct tracer what to do.

/planet will be forwarded to planetarium client.
/nozoid will be forwarded to nozoid client.

0 : display user pointlist with current client key. See below for client key.
1 : pull in redis a new correction matrix (EDH) 
2 : display black 
3 : display grid
4 : resampler 
5 : pull in redis a new client key


/pl/clientnumber/lasernumber value : value is the pointlist to draw as string type. For string format see code in clients directory.

Example : client 0 send 2 point lists one for laser 0 and one for laser 1 by sending in redis :
/pl/0/0 and /pl/0/1
The "client key" when client 0 is selected to be displayed by lasers is "/pl/0/". 
Each tracer pull its pointlist by using the current client key "/pl/0/" 
and add its laser number at startup : /pl0/0 ant /pl/0/1

"Client" is a concept. Imagine in a demoparty there is 4 lasers. 
John and Paul want to draw on all lasers. 
Let's give John client 0, he will send points to /pl/0/0, /pl/0/1, /pl/0/2 and /pl/0/3.

Paul is client 1, so he will use /pl/1/0, /pl/1/1, /pl/1/2 and /pl/1/3.

Both can send their pointlists to redis server.
When John get the lasers switch to client 0, when it's Paul turn switch to client 1.

But say Bob and Lisa needs only 2 lasers each. Give them client 2. 
Bob could use /pl/2/0 and /pl/2/1 and Lisa could use /pl/2/2 and /pl/2/3.
