[Java]PixeloMatic - Psycho_Coder - 05-26-2013

Well I made something in Java but I don't know what this actually is ??. I was developing something and as a byproduct this came up. Don't know what to call but still I named this PixeloMatic since I am playing with pixels. If you come up with a better name do tell me.

Code:
import java.awt.*;
import java.applet.*;
import java.awt.image.*;

public class PixeloMatic extends Applet implements Runnable {

    int pixl2[] = new int[256];
    Thread t = null;
    final int width=500, height=500;
    Image buffer = null;
    int pixl1[],pixlook[];
    

    @Override
    public void init() {
        setSize(500, 500);
        int r, g, b, i;
        pixl1 = new int[width * height];
        pixlook = new int[width * height];
        
        for (i = 0; i < 256; i++) {
            r = (int) (128 + 128 * Math.sin(Math.PI * i / 32.0));
            g = (int) (128 + 128 * Math.sin(Math.PI * i / 64.0));
            b = (int) (128 + 128 * Math.sin(Math.PI * i / 128.0));
            pixl2[i] = (255 << 24) | (r << 16) | (g << 8) | b;
        }

        for (r = 0; r < height; r++) {
            for (g = 0; g < width; g++) {
                i = (int) (128 + 128 * Math.sin(r / 16.0) + 128 + 128 * Math.sin(g / 16.0));
                i = i / 2;
                pixlook[g + r * height] = i;
            }
        }
    }

    @Override
    public void start() {
        t = new Thread(this);
        t.start();
    }

    @Override
    public void run() {
        while(true) {
            try {
                repaint();
                Thread.sleep(2);                
            } catch (InterruptedException e) {
            }
        }
    }

    @Override
    public void stop() {
        t = null;
    }

    @Override
    public void paint(Graphics g) {
        update(g);
    }

    @Override
    public void update(Graphics g) {
        int i, x, y, t;
        for (y = 0; y < height; y++) {
            for (x = 0; x < width; x++) {
                t = x + y * height;
                pixl1[t] = pixl2[pixlook[t]];
            }
        }
        buffer = createImage(new MemoryImageSource(width, height, pixl1, 0, width));
        g.drawImage(buffer, 0, 0, this);
        int tmp;
        tmp = pixl2[0];
        for (i = 1; i < 256; i++) {
            pixl2[i - 1] = pixl2[i];
        }
        pixl2[255] = tmp;
    }
}

Thats a nice effect. I'm not understanding the code. I will soon understand java.
Thank you.

Pretty cool Smile

Now you can get into water refraction and ripple effects for games. The theory is pretty cool behind all of that stuff. I was looking at formulas for heat haze a week ago.

Sir may I ask what is HeatHaze ? Is it your new project. Just asked out of curiosity. Confused

OOP's since it had "haze" so I thought it was some project of yours :lol:

But these effects are awesome. Refraction is such an awesome thing. If I go through the algorithms of these effects then I can create some effects that we have in PS. Cool

Cool

RE: [Java]PixeloMatic - ArkPhaze - 06-03-2013

Most of the time you see refraction with water. It's mainly caused by a difference in medium densities though. And in combination with light, it creates some optical effects. That's one of the reasons why I like game programming; applying real world concepts to the virtual world.

RE: [Java]PixeloMatic - Deque - 06-03-2013

That looks pretty cool. I would probably call it LSD trip. Tongue

But codingwise you did the some mistakes again that I already criticised in your last code: No access modifiers, magic numbers everywhere.
Good: You took care to use @Override.

RE: [Java]PixeloMatic - Buster - 08-01-2013

I really like your code, would you mind if I use your source code?

Yes you can use it.
