my first post:)
1, to get realtime data of led and image (python)
Code
ws.send('{"command":"ledcolors", "tan":2,"subcommand":"ledstream-start"}')
ws.send('{"command":"ledcolors", "tan":1,"subcommand":"imagestream-start"}')
2, to draw light effect with each "light"
JavaScript
var grd=ctx.createRadialGradient(x,y,2,x,y,r);
grd.addColorStop(0,"rgba("+leds.slice(idx*3,(idx+1)*3).join(',')+",0.1)");
grd.addColorStop(0.5,"rgba("+leds.slice(idx*3,(idx+1)*3).join(',')+",0.02)");
grd.addColorStop(1,"rgba("+leds.slice(idx*3,(idx+1)*3).join(',')+",0)");
