Hi,
I have built multiple programs with music using minim with processing. However, I just downloaded the newest version, processing 2, and the player is not working. I get a message saying "nullPointer". is the code for using minim different with the latest version of processing?

Hi,
I am trying to run a 3D program with opengl, however it doesn't seem to be working. I cannot find the opengl library anywhere in my processing folders. I am on a HP Dv7 laptop with an intel Core i7 processor and Radeon Graphics. Is my computer capavle of running them? and if so, how do I make it work?

Hi, I have built an audio visualizer, however for some reason I keep getting the message in the subject line sometimes while running certain parts of the program. Here is a bit of code that seems to be the issue. Could you take a look and tell me if you have any possible solution please?

voi draw() {

for (int i = 0; i < iMax; i++) {

band = fft.getBand(i/dF);

}

if (vis == 3) {

// stroke(0, 0, 255);

rotateZ (0);

xS = 10;

dF = 1;

bW= 30;

iMax=200;

band =constrain(band, 0, 20);

Spacing = 3;

stroke(black);

///// DRAW 3D RECTANGLE BASED ON BAND VALUE //// (IM)

// Front

pushMatrix();

if (visName==3) {

translate(200, height/2, 0);

rotateY(ryc);

translate(-(200), -height/2, 0);

}

else if (visName==3.1) {

rotateY(0);

}

constrain(bW*band, 0, 20);

pushMatrix();

beginShape();

vertex(xS*i+10, height/2 - bW*band, -width/10);

vertex(xS*i+10, height/2, -width/10);

vertex(xS*i-10, height/2, -width/10);

vertex(xS*i-10, height/2 - bW*band, -width/10);

vertex(xS*i+10, height/2 - bW*band, -width/10);

endShape();

// Back

beginShape();

vertex(xS*i+10, height/2 - bW*band, -width/10-10);

vertex(xS*i+10, height/2, -width/10-10);

vertex(xS*i-10, height/2, -width/10-10);

vertex(xS*i-10, height/2 - bW*band, -width/10-10);

vertex(xS*i+10, height/2 - bW*band, -width/10-10);

endShape();

// Right

beginShape();

vertex(xS*i+10, height/2 - bW*band, -width/10);

vertex(xS*i+10, height/2 - bW*band, -width/10-10);

vertex(xS*i+10, height/2, -width/10-10);

vertex(xS*i+10, height/2, -width/10);

vertex(xS*i+10, height/2 - bW*band, -width/10);

endShape();

beginShape();

vertex(xS*i-10, height/2 - bW*band, -width/10);

vertex(xS*i-10, height/2 - bW*band, -width/10-10);

vertex(xS*i-10, height/2, -width/10-10);

vertex(xS*i-10, height/2, -width/10);

vertex(xS*i-10, height/2 - bW*band, -width/10);

endShape();

// Bottom

beginShape();

vertex(xS*i-10, height/2, -width/10);

vertex(xS*i-10, height/2, -width/10-10);

vertex(xS*i+10, height/2, -width/10-10);

vertex(xS*i+10, height/2, -width/10);

vertex(xS*i-10, height/2, -width/10);

endShape();

popMatrix();

}

}
