First off, thanks for the amazing book! I've had a lot of fun going through it.
I was just wondering if this is how the gradient from chapter 10 should look. Is it supposed to repeat?

Yup! That's correct. Remember that we constrain the gradient to start at "0" and end at "1", so without any scaling it'll repeat starting at every whole numbered x-coordinate (running from 0 to 1, 1 to 2, 2 to 3, etc.). If you want it to be wider, scale (and possibly translate) it in x.

An example of how one can mirror the gradient, should anyone find it useful.  if(Math.Abs(p.X - Math.Floor(p.X)) < 0.5)
return a + (b - a) * (2 * p.X - Math.Floor(2 * p.X));
else
return b + (a - b) * (2 * p.X - Math.Floor(2 * p.X)); |
