Noise
A dithered terrain print
In this lesson
Draw every place the noise crosses a value. Instant topography. We build it live in about 13 minutes, then you change it in the Lab until it is yours.
Try this after
Change one number at a time and write down what it did. Most of the good surprises in this course come from the third or fourth change, not the first.
