I started experimenting with the SoundMixer.computeSpectrum() function and created a very simple visual effect. Make sure you have some kind of sound playing in your browser for it to work! I recommend some Squarepusher or Aphex Twin

It was tested listening mostly to:  “The Exploding Psychology”

Edit: Will not work in IE for reasons unknown to me. Get a real browser
I will embed a default tune in future experiments

I plan on doing (many?) more of these in the future. I also plan on making them (much?) more interesting. For now this is a decent proof of concept.

	function onEnterFrame(e:Event) {
		SoundMixer.computeSpectrum(byteArray, false);

		var drawCanvas : Shape = new Shape();

		var matrix = new Matrix();
		matrix.createGradientBox(768, 1);

		drawCanvas.graphics.lineStyle(1);
		drawCanvas.graphics.lineGradientStyle(GradientType.LINEAR,
			[0x005599, 0x8888FF, 0x005599],
			[0, 1, 0],
			[0, 128, 255],
			matrix);
		drawCanvas.graphics.moveTo(0, 160);

		for (i in 0...256) {
			var t:Float = byteArray.readFloat();

			var controlX = i*3;
			var controlY = 0 + 160;

			var xx = (i + 1) * 3;
			var yy =  t * 200 + 160;

			drawCanvas.graphics.curveTo(controlX , controlY, xx , yy);
		}

		bitmap.bitmapData.applyFilter(bitmap.bitmapData, bitmap.bitmapData.rect, new Point(), blurFilter);
		bitmap.bitmapData.draw(drawCanvas,new Matrix(),colorTransform);
	}

Just a very simple tutorial about a very simple subject that can catch an unaware noob (such as myself) off guard:

My posts should now automatically post to my facebook wall. In order to do this I needed to create a facebook app.

The funny thing is that after creating said app I needed to authorize it.. And it actually took me a second to click the ‘allow’ button…

Aka “How to waste precious coding time designing something worthless”

Click to visit project page and try demo

But hey.. you wouldn’t know it yet but this IS supposed to be a procedural generation blog

Features (If they can be called that)

• Setting and visualization of all perlin noise parameters in real time
• Offset animation
• Merging of 3 separate noise patterns for complex perlin effects
• Randomize button so you don’t have to deal with my Ui

Soooo Here is my first post and while I’m at it the first version of my first project in Haxe

A pretty dang fast and flexible port of this: A-Star (A*) Implementation in C#.
Still needs some work but I’m happy with the current results.

Features

• Weighted nodes
• Choice of allowing or not allowing diagonal movement
• Choice of adding ‘weight’ to diagonal moves to deter from using them
• Choice of punishing any change in direction to promote straight paths when possible
• Implementation of a ‘ Tie Breaker ‘
• Multiple built in heuristic methods
• Possibility of limiting the nodes the pathfinder may test (returning no path when the limit is reached)
