# Moiré Processing

Using Processing to produce Moiré patterns.

Processing code:

//moiré maker by kjanzen, 2012 //Drawing two sets of lines at varying angles and spacings. (see settings) //Press 'p' to save as PDF. (saves to sketch directory) import processing.pdf.*; void setup() { size(1280, 720); //size (pixels x pixels) background(255); //backgtound colour (0 = black, 255 = white) } void keyPressed(){ if (key=='p'){ //press 'p' to save PDF (saves to sketch dir) beginRecord(PDF, "moire.pdf"); //save PDF as ('name'.pdf) } } void draw() { //settings int angle1 = 0; //adjust angle for set1 (<20) int angle2 = 0; //adjust angle for set2 (<20) int spacing1 = 10; //adjust spacing for set2 int spacing2 = 7; //adjust spacing for set2 int shift1 = 1; //adjust shift for set1 (!=0) int shift2 = 1; //adjust shift for set2 (!=0) //set1 for (int i=0; i<width+1500; i+=spacing1) { stroke(0); pushMatrix(); // move the origin to the pivot point translate(0, -500); // then pivot the grid rotate(radians(angle1)); // and draw the square at the origin line(i, 0, i/shift1, width+1500); popMatrix(); //set2 for (int j=0; j<width+1500; j+=spacing2) { stroke(0); pushMatrix(); // move the origin to the pivot point translate(0, -500); // then pivot the grid rotate(radians(angle2)); // and draw the square at the origin line(j, 0, j/shift2, width+1500); popMatrix(); } } endRecord(); }
