/**
|
|
* This demo creates a dynamic graphical output utilizing simplex and
|
|
* linear interpolation-based color ranges.
|
|
*
|
|
* Functionalities:
|
|
* - Defines a list of base colors converted to LAB color space for smooth interpolation.
|
|
* - Constructs a 3D simplex range and a 2D linear range for color sampling.
|
|
* - Randomly populates two sections of the screen with rectangles filled with colors
|
|
* sampled from simplex and linear ranges respectively.
|
|
* - Draws a vertical divider line in the middle of the application window.
