Hey,
first post here in the forum. I tried to make 3d music visualisation. Its working but some of thepatches or quads in my case
are not drawn, or are not there? I dont really understand it because it should iterate through and the fft size is stays the same.
so here what if got till now...

player.loop();
fft = new FFT (player.bufferSize(), player.sampleRate());
fft.logAverages(12,12);

println("anfang");

waves.add(w);

endShape();
}
}
}
}
class Wave{

PVector col = new PVector(random(255),random(255),random(255));;

createWave(zpos);
}
void createWave(float zpos){
fft.forward(player.mix);
pts = new PVector[fft.avgSize()];
float theta = 0;
float t = fft.avgSize();
float plus = 360/t;
for (int i=0; i< fft.avgSize(); i++){
int r = int( fft.getAvg(i)+100);
float x = r * cos(radians(theta));
float y = r * sin(radians(theta));
PVector tp= new PVector(x,y,zpos);

stroke(col.x,col.y,col.z);
strokeWeight(1);
line (p.x,p.y,p.z,mp.x,mp.y,mp.z);
}
}
}
}
thanks for any kind of advice
and im using the 1.5.1 Version of Processing
