Joining lines
In the previous example, I also used a conditional statement to keep looping through the
caps arrays. Since each end cap was output three times, I needed to keep resetting
the array counter back to 0, which is exactly what the conditional statement does:
if (j>2){
j=0;
}
The next sketch, shown in Figure 6-25, illustrates the joining implications of the different
end caps. In addition, the sketch implements a column layout algorithm, with simple
padding between the corresponding cells. Try changing the value of the strokeWeight()
argument as well as the shapes and padding variables to see what happens.
