Gradient of a line python
WebThe gradient that you are referring to—a gradual change in color from one part of the screen to another—could be modeled by a mathematical gradient. Since the gradient gives us the steepest rate of increase at a given point, imagine if you: 1) Had a function that plotted a downward-facing paraboloid (like x^2+y^2+z = 0.
