Lesson 1.2

Modifying size along height:

int gridW = 12;
int gridH = 12;
int border = 60;
int stepX = 60;
int stepY = 60;
float sizeModifier = 1.05;
int graphicSize = 30;


void setup()
{
size(800,800);
noStroke();
fill(0);
background(255);
rectMode(CENTER);
float graphicSizeScaled = graphicSize;
translate(border, border);
for(int i=0;i < gridH;i++)
{
for(int j = 0;j < gridW;j++)
{
rect(j * stepX, i * stepY, graphicSizeScaled, graphicSizeScaled);
}
graphicSizeScaled *= sizeModifier;
}
}
