Animated Color Procedural Texture

Author: Antony Stewart

Description

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

Usage

Attach this script to the object that you wish to give a special effects color. Write maths functions in between for the red, blue, green variables that compute between 0 and 1, based on x,y, graphs. pastel colors are closer to 0 and bright colors closer to 1. for example if you want a psycadelically angry robot, make a black and red dot graph and make move in Time.time*50, i.e. warping very fast. You need to know abit about 2D graphs, straight =sin(x*10) vertical =sin(y*10) oblique = sin(x+y) or (x-y) wiggle = sin(x*10+sin(y*5)*3) complex wiggles = add multiple wiggles together.

JavaScript - AnimatedTextureUV.js

<javascript>

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

var lacunarity = 6.18; var h = 0.69; var octaves = 8.379; var offset = 0.75; var scale = 0.09;

var offsetPos = 0.0;

private var texture : Texture2D; private var perlin : Perlin; private var fractal : FractalNoise;

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*50+Time.time+Mathf.Sin(y*30)*4)/5+.5; var blue = Mathf.Sin(x*50+Time.time+Mathf.Sin(y*30)*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>
