# farcar – Interruptions

Observations:

- The lines are black
- The lines have thin strokes
- The lines are equal lengths
- The lines are ordered on a grid-like system
- The lines face arbitrary directions
- Some areas are patches lacking any lines
- The canvas is a light grey
- The canvas is square
- The lines formed closed shapes
- There is a small bleed area between the lines and the edge of the canvas

Program:

Process:

In remaking this work, I laid out a grid where lines of equal lengths facing arbitrary directions would be drawn out. To make for the patches the original drawing had, I gave the program a 70% chance of drawing a line at each coordinate. While I felt that I represented this project well, I wanted to do more with it. I felt that the patches were one of the highlights of the piece, and wanted there to be a slight component of interactivity. As a result, I made it such that the location the user clicks on to activate a new piece will generate a gap in that area, and stay there after each successive generation. Not only was the user generating a new piece, but they were helping to make it too.

Code:

//saves the locations of where you clicked var gapX = [] var gapY = [] //draws a stream of lines using two for-loops function setup(x, y) { createCanvas(500, 500); background(225); var tempX = []; var tempY = []; var tempW = []; var tempH = []; //randomly creates areas to place gaps var end = random(15); for(var h = 0; h < end; h++) { append(tempX, random(500)); append(tempY, random(500)); append(tempW, random(30)); append(tempH, random(30)); } append(gapX, x); append(gapY, y); for(var i = 0; i < width; i+=6) { for(var j = 0; j < height; j+=7) { //checks for overlap with gaps, and gives it a 70% chance of drawing a line var overlap = false; var chance = random(); //checks overlap agains every gap pos for(var k = 0; k < gapX.length; k++) if(gapX[k]-30 < i && i < gapX[k]+30 && gapY[k]-30 < j && j < gapY[k]+30) overlap = true; for(var l = 0; l < tempX.length; l++) if(tempX[l] - tempW[l] < i && i < tempX[l] + tempW[l] && tempY[l] - tempH[l] < j && j < tempY[l] + tempH[l]) overlap = true; if(!overlap && (chance < 0.7)) lineByAngle(i, j, random(1/4*PI,3/4*PI), 20); } } } //resets upon click function draw() { if(mouseIsPressed) setup(mouseX, mouseY); } //draws line based on an (x,y) origin pair in a radial system function lineByAngle(x, y, rad, len) { line(x,y,x+len*sin(rad),y+len*cos(rad)); } |
