Playing around with ofxMPMFluid to create a displacement map for a sphere.

Download the gif_recorder_source.zip for processing 2.0a4.

Download the application ~(35MB). Pretty big file size for such a simple app.

We displayed Twelement and many clever tweets that showed up in real time on the large projection.

We also did a processing workshop.

A quick app just in time for the holidays. Blinking your eyes creates berry branches and moving your eyebrows up and down makes thin branches. The colors of the branches are based on the camera feed. Moving your head influences the direction of the branches. A slight clockwise or counter-clockwise force is applied to help obtain the “wreath” effect.

Download the mac osx WreatherHead app to make your own.
Not compatible with osx Lion.

Made with openFrameworks openframeworks.cc/

There are many ways to do this and other examples using OpenFrameworks in this thread. My approach was a little more complicated than it should have been, but it worked. I used the following to get the paths of the letters for any font:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

<code>
ofPath path = font.getCharacterAsPoints(letter);
vector <ofPolyline> polys = path.getOutline();
// resample the font points so that we have a point every (x) pixels;
for (int i = 0; i < polys.size(); i++) {
 
	// now resample and draw new dots
	ofPolyline sampled = polys[i].getResampledBySpacing(samplePixels);
	sampledPolys.push_back( sampled );
	// outline
	for (int j = 0; j < sampled.size(); j++) {
		points.push_back( ofVec3f(sampled[j].x, sampled[j].y, 0.));
	}
}
</code>

I also draw the letter into an FBO for later use. I triangulate the points using ofxDelaunay and remove points if they are not inside the letter polygon. After that, I simply duplicate the remaining points and move them in z-space to make the extrusion. Check out the example below for the full source.

Check out some of the images.

Follow This! is a first person shooter game utilizing the Microsoft Kinect camera. Input a twitter search term to create birds, varying based on the loaded tweets. Once all of the tweets have been gathered, you are equipped with gatling gun arms. Aiming your arms in physical space is reflected in the game. Open your hands to fire and pulverize as many birds as possible, earning score multipliers for quick hits. You must blast an increasing minimum amount of birds to advance to the next level, if not, fail whale; game over.

Curious, having trouble, a debug screen displays the various digital images generated by the Kinect camera and provides some brief instructions / help.

Thanks for all the help from the OF community!

The game uses the Kinect for user control

Users control their gatling gun arms independently by aiming their arms in physical space and fire by opening their hands.

Earn score multipliers by shooting birds in rapid succession.

When users have their hands closed, the guns do not fire.

The red rocket bird explodes into bird-seeking rockets when shot.

Shoot birds quickly to get a kill frenzy.

Check out the top highscores.

In this application, the text is dynamically created in 3D by using ofxDelaunay triangulation and then extruding along the text outline. I tested it on 5 fonts, two of them being rather complex outlines and it worked with a good amount of accuracy. There is a breakdown of the 3D text creation process at the end of the video, although it is not very descriptive, you get the general idea.

Both the decomposition of the dynamic text and loaded 3D models is done on the fly and is based on the examples provided by Bullet.

Didn’t spend too much time on the sounds as you can probably tell.

First I made a sketch in pencil and scanned it in.



Then I traced it in Adobe Illustrator to make the stencil for the laser cutter.
