Fabric

I learned Perlin Noise last week, so I want to use Noise() function to create may my pattern.  I try to imitate the interaction between a person and the fabric. The movement of the mouse can be like a person touching the fabric. At first, the pattern appears static. When you move the mouse, the fabric wrinkles and starts to move. I use the mouseY parameter to simulate the force of touch. The bigger the value of mouseY, the bigger the force of touching, so the amplitude of the changing pattern also becomes larger.

This time, I use HSB mode to control color, which is much easier to control than RGB mode.
