This is a mod of the procedural perlin noise demo script, to generate textures with mixes of RGB by blending 3 independant RGB x,y, graphs.


Attach this script to the object that you wish to give a special effects color. Write maths functions for the red, blue, green variables that compute between 0 and 1, based on x,y, graphs. pastel colors are closer to .7 and bright colors closer to 1. for example if you want a psycadelically angry robot, make a black and red dot graph and animate with Time.time*50, i.e. warping very fast. You need to know abit about 2D graphs.

straight =sin(x*.3)

vertical =sin(y*.3)

oblique = sin(x+y) or (x-y)

wiggle = sin(x*.2+sin(y*.5)*.3)

complex wiggles = add multiple wiggles together.

Note: x and y =128 so sensible sine multipliers are 0.1,0.345 etc, not 20.


JavaScript - AnimatedTextureUV.js


var gray = true; var width = 128; var height = 128;

private var texture : Texture2D;

function Start () { texture = new Texture2D(width, height, TextureFormat.RGB24, false); renderer.material.mainTexture = texture; }

function Update() { Calculate(); }

function Calculate() {

for (var y = 0;y<height;y++) { for (var x = 0;x<width;x++) { if (gray) { var red = 0; var green = Mathf.Sin(x*.5+Time.time+Mathf.Sin(y*.23)*.8)/5+.5; var blue = Mathf.Sin(x*.3+Time.time+Mathf.Sin(x*.43)*.4)/5+.5;

texture.SetPixel(x, y, Color (red, green, blue, 1)); } else {

texture.SetPixel(x, y, Color (1, 0, 0, 1)); } } }

texture.Apply(); } </javascript>
