Executable demo

Well, after sleeping about 10 hours in 3 days, I better sleep a bit more today as I think tomorrow (friday) will be a kind of party coding day/night (sponsored by red bull). Now that I think about it... it may be the first time I actually do coding when doing partycoding :P

The demo system now works everywhere: Windows / MacOS / Linux...

/projects/inspire08/08/demo.zip

So, tomorrow... content content content, and I guess I won't do the log so there is a bit of surprise for the competition (hopefully).

Executable demo

I guess the organisers are expecting executable demos instead of a link on a browser. This is something I had no idea of how to do. But while checking Ne-He's Outline font tutorial, this time the JoGL example had a .bat with a command line that execute the thing on a window. This may sound totally normal to you, but it was exciting to me O:) So I quickly analysed it and extracted the logic and managed to make my demo.jar run directly on Windows!

After tweaking a bit the folders so it looked a bit nicer (I put all the libs (even linux/mac universal inside a /libs folder) the command looks like this:

java -Djava.library.path=.\libs -cp .\demo.jar;.\libs\jogl.jar;.\libs\gluegen-rt.jar MainWindow

This version should already work on Windows:

/projects/inspire08/08/demo.rar

... I'll do the launchers for Mac/Linux later on. uhm... Windows/Mac/Linux/Online, I like how that sounds :P And with all the libraries there ready to run on all the OS the filesize is 5Mb zipped (including the 4Mb OGG), sounds good to me too.

Effects

Here we go with some effects... dots and HypnoRays. The demo is not supposed to look like this btw, I'm just adding effects on top of each other by now.

/projects/inspire08/07/

I may try to avoid loading images for this prod... I don't know... It's late tho, time to sleep.

Oh, here is the code for the hypnoray, it's just an idea I had on the bus on the way home today (vertex colors power ;D).

package effects;

import javax.media.opengl.GL;

import com.xplsv.utils.Timer;

import core.Vertex;

public class EffectHypnoRays extends Effect
{
	private Vertex[] meshData;
	
	public EffectHypnoRays(GL gl, int start, int duration)
	{
		super(gl, start, duration);
	}
	
	public void init()
	{
		int sides = 200;
		int radious = 4;
		float angle = ( 360.0f / (float)(sides-1) ) * ( (float)Math.PI / 180.0f );
		
		meshData = new Vertex[sides+1];
		
		Vertex v = new Vertex();

		v.position.x = 0.0f;
		v.position.y = 0.0f;
		v.position.z = 0.0f;

		v.colour.r = 0.0f;
		v.colour.g = 0.0f;
		v.colour.b = 0.2f;
		
		meshData[0] = v;
		
		for (int i = 1; i <= sides; i++)
		{
			v = new Vertex();

			v.position.x = (float) (radious * Math.cos(i * angle));
			v.position.y = (float) (radious * Math.sin(i * angle));
			v.position.z = 0;			

			v.colour.r = (float)Math.random() + (float)Math.sin(i*.5) - 1.0f; 
			v.colour.g = v.colour.r;
			v.colour.b = v.colour.r + 0.2f; 

			meshData[i] = v;
		}
	}
	
	public void render()
	{
		if(!active())
			return;
		
		gl.glLoadIdentity();
		gl.glTranslatef(0.0f, 0.0f, - 5.0f);
		gl.glRotatef((float)(Timer.get()*.01f), 0.1f, 0.0f, 1.0f);
		
		gl.glBlendFunc(GL.GL_SRC_ALPHA, GL.GL_ONE);
		gl.glBegin(GL.GL_TRIANGLE_FAN);

		for (int i = 0; i < meshData.length; i++)
		{
			gl.glColor4f(meshData[i].colour.r, meshData[i].colour.g, meshData[i].colour.b, 1.0f);
			gl.glVertex3f(meshData[i].position.x, meshData[i].position.y, meshData[i].position.z);
		}

		gl.glEnd();
	}
}

Pasarte medio año escribiendo comentarios fake tan estupidos como estos para animar tu concurso, no tiene precio ;)

Y quiero pensar que son fake y que la gente no es asi en realidad...

Timeline, ColorFades, Flashes!!

Well, if you re-checked my previous log you know that I found a quick way to put together the whole demo. There is still hope! :D

I did a quick test of having 100 effects checking if they had to be rendered or not per frame and the performance was really good, like 60fps. So, as I don't think I'll get 100 effects on the timeline I guess it's good enough to use this way for this prod. God bless Eclipse and it's refactoring/rename tool, because I've renamed the SceneManager class a couple of times... It's now called Timeline and it looks like this:

import javax.media.opengl.GL;
import java.util.ArrayList;

import effects.*;

public class Timeline
{
	private ArrayList effects;

	public Timeline(GL gl)
	{
		effects = new ArrayList();
		
		effects.add( new EffectRandomPolys(gl, 0, 27700) );
		effects.add( new EffectColourFade(gl, 0, 10000, 1.0f, 0.0f, new float[] {0.0f,0.0f,0.0f}) );
		
		effects.add( new EffectFlash(gl, 14450, 2000, 0.5f, 0.0f, new float[] {0.0f,0.0f,1.0f}) );
		
		effects.add( new EffectRandomPolys(gl, 27700, 30000) );
		effects.add( new EffectFlash(gl, 27700, 2000, 1.0f, 0.0f, new float[] {1.0f,1.0f,1.0f}) );
		
		effects.add( new DebugInfo(gl, 0, 0) );
		effects.add( new DebugLogger(gl, 0, 0) );
	}

	public void init()
	{
		for (int i = 0; i < effects.size(); i++)
			((Effect)effects.get(i)).init();
	}

	public void render()
	{
		for (int i = 0; i < effects.size(); i++)
			((Effect)effects.get(i)).render();
	}
}

Yep! I have ColourFades and also Flashes :D (The diference is that one is on additive blending ant the other isn't).

This is how the thing looks like now:

/projects/inspire08/06/

Not much there yet, but it's a base. Now, it's really about time to do more effects, learn how to load/display images and find out how to jump to a middle part in the tune.

Base code, file handling

Right... End of the 3 day weekend. Things are not looking too promising in order to have something releasable for the deadline... I'm doing some progress here and there, but I still need a lot of practice with Java.

Still having problems loading assets... but well, I'm too old to lose sleep time for reaching the deadline :P My invtro for D/// will have to be released somewhere else... Maybe at Euskal??? I'll take my time, maybe I'll just do a teaser, or something else for the party. We'll see.

EDIT: Funny that, after saying I wasn't going to lose sleep time I ended up going to sleep at 4.30 :P Not doing demo stuff tho, mainly reading stuff like this. Anyway, while trying to sleep I was thinking that a quick way to have some synch in place would be just adding start/duration parameter to the effects... avoiding any kind of XML script+resource manager. Something like this:

effects.add(new EffectFlash(gl,19207,1000);

And then, the effect instance would be checking itself if it needs to be rendered or not (per frame). It's very crappy way of doing it, as I may end up with 50 effects asking if they need to be rendered... but well, I'll fix that on the next one. At least it gives some hope to the prod.

I have googled a bit in order to do this, but all the info I was finding was a bit obsolete, so use this info if you want, but the main purpose of writting this down is so I can remember it next time (hopefully without being obsolete):

After installing Apache2 from synaptic...

sudo gedit /etc/hosts

Add line...

127.0.0.1	ricardocabello.local

then...

sudo gedit /etc/apache2/sites-available/ricardocabello

with this kind of content...

<VirtualHost *>
	ServerName ricardocabello.local
	DocumentRoot /home/mrdoob/Desktop/www/ricardocabello.com/
</VirtualHost>

save the file, and then...

sudo a2ensite

chose ricardocabello (this will mainly create a link on sites-enabled). And then, to complete the task:

sudo /etc/init.d/apache2 reload

Base code (still!)

Well, I haven't progressed much visually, but I've refactored everything quite a bit. The base is almost done.

/projects/inspire08/05/

As you can see, I have a Logger, Timer, FPS counter, MS... That's enough for debugging/testing the effects on-the-fly. Also, I have a base for the Scene Managing, I still have to load a XML with the times of start/end and all this but by now it's simple enough and looks like this:

import javax.media.opengl.GL;
import java.util.ArrayList;
import com.xplsv.utils.Logger;

import scenes.*;

public class SceneManager
{
	private ArrayList scenes;

	public SceneManager(GL gl)
	{
		scenes = new ArrayList();
		
		scenes.add(new SceneRandomPolys(gl));
		scenes.add(new SceneInfo(gl));
		scenes.add(new SceneLogger(gl));
	}

	public void init()
	{
		Logger.init();
		Logger.log("SceneManager.init");
		
		for (int i = 0; i < scenes.size(); i++)
			((Scene)scenes.get(i)).init();
	}

	public void render()
	{
		for (int i = 0; i < scenes.size(); i++)
			((Scene)scenes.get(i)).render();
	}
}

Just 4 days to go and I still don't know how the visual content will be... Oh well... Tomorrow more.

Base code

Although my mind was trying to avoid working on the thing today, I managed to concentrate a bit. As getting the milliseconds elapsed in the tune seemed to be something I couldn't achieve at the moment, I decided to look for a workaround which I could fix in the future. Found out the AS3 getTimer() equivalent in Java (System.currentTimeMillis()), so by now, I would depend of the music not being delayed and keeping the same timer as Java has (crossing fingers). So I did a simple class like to get going.

So, tomorrow I should be doing a quick SceneManager and also some Scenes/Effects finally :P

I hope I also find out soon how to jump to a defined part of the tune too :S
