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