Hi, 

I'm using a processing for quite a while, but this time, I'm stucked.

I'm trying to do something like stripes on lower part of this image, generaly stripes with kinda perspective distortion. I used for loop to generate coordinates for x-axis for quads, but for some reason, quads are drawing across each other, almost like connected to each other. This is a source code:

1. void setup() {
   size(400,400);
   smooth();
   }
   
   void draw() {
   background(255);
   skewY(120);
   cube(-200,-100);
   
   }
   
   void cube(float xpos, float ypos) {
   pushMatrix();
   scale(2);
   translate((width/2)+xpos, (height/2)+ypos);
   
   float tall = 40;
   float y1 = -tall;
   float y2 = tall;
   
   
   
   for(int i = 16; i < 32; i = i+8) {
   for(int j = 0; j < 64; j = j+32){
   strokeWeight(0.5);
   
   quad(0+i, y1, 6+i, y1, 6+j, y2, 0+j, y2);
   }
   }
   popMatrix();
   }
   

Hope anyone can help me figure this one out.

Thanks in advance forum!
