As mentioned before in “Tilings and their duals” we can only use finite parts of tilings and we need a method to decide whether a line should be included or not. For this I have built a function “inside(Vector a,Vector b)”, where a and b are the Positions of the endpoints of the line. It returns the boolean value “true” if the line has some points inside the rectangle xRange Setting up the coordinates – the modified code“. Then, this rectangle fits exactly the screen. For debugging, we can decrease xRange and yRange to see better what happens at the boundary. You will find the code in the next post.
