/**
|
||
* A multi-color gradient mapped into smooth, animated curves built as a combination of 2 Simplex noises.
|
||
*
|
||
* Fragment shader uniforms:
|
||
* - u_time (float): Animation time
|
||
* - u_scale (float): Overall zoom level, used for anti-aliasing calculations
|
||
* - u_colors (vec4[]): Up to 10 base colors in RGBA
|
||
* - u_colorsCount (float): Number of active colors
|
||
* - u_stepsPerColor (float): Number of extra colors between base colors, 1 = N colors, 2 = 2×N, etc. (1 to 10)
|
||
* - u_softness (float): Color transition sharpness, 0 = hard edge, 1 = smooth gradient (0 to 1)
|
||
*
|
||
* Vertex shader outputs (used in fragment shader):
|
||
* - v_patternUV (vec2): UV coordinates for pattern with global sizing (rotation, scale, offset, etc) applied
|
||
*
|
||
* Vertex shader uniforms:
|
||
* - u_resolution (vec2): Canvas resolution in pixels
|
||
* - u_pixelRatio (float): Device pixel ratio
|
||
* - u_originX (float): Reference point for positioning world width in the canvas (0 to 1)
|
||
* - u_originY (float): Reference point for positioning world height in the canvas (0 to 1)
|
||
* - u_worldWidth (float): Virtual width of the graphic before it's scaled to fit the canvas
|
||
* - u_worldHeight (float): Virtual height of the graphic before it's scaled to fit the canvas
|
||
* - u_fit (float): How to fit the rendered shader into the canvas dimensions (0 = none, 1 = contain, 2 = cover)
|
||
* - u_scale (float): Overall zoom level of the graphics (0.01 to 4)
|
||
* - u_rotation (float): Overall rotation angle of the graphics in degrees (0 to 360)
|
||
* - u_offsetX (float): Horizontal offset of the graphics center (-1 to 1)
|
||
* - u_offsetY (float): Vertical offset of the graphics center (-1 to 1)
