Lesson 1.3
Modifying rotation:int gridW = 14; int gridH = 14; int border = 70; int stepX = 50; int stepY = 50; int graphicSize = 25; void setup() { size(800,800); noStroke(); fill(0); background(255); rectMode(CENTER); float rotation = 0; translate(border, border); for(int i=0;i < gridH;i++) { for(int j = 0;j < gridW;j++) { rotation++; pushMatrix(); translate(j * stepX, i * stepY); rotate(radians(rotation)); rect(0, 0, graphicSize, graphicSize); popMatrix(); } } }
