Just a couple of weeks to go to the gotoAndSki() conference in Stechelberg Switzerland. An awesome conference combining skiing, networking and presentations. Should be good fun! I have the privilege to be one of the speakers. Here’s what I will be talking about: Microsoft’s Kinect allows players to interact without using any controllers. Hackers were [...]

Here’s another Kinect experiment. This time a Kinect make-over of the best game ever, Tetris. OpenCV is used for facial recognition. The depth value is then retrieved from the depth buffer by using the center point. The camera changes according to the face’s position. Simple gestures are recognised and used to control the position & [...]

My second OpenKinect experiment. OpenCV is used to recognise the print on the Obey t-shirt. The center of the rectangle that contains the recognised object is used to get the depth value from Kinect’s depth buffer. Two other depth values are then used to get the current y rotation. I know scaling and rotation can [...]

Finally got to mess around with the Kinect I bought. It’s a great opportunity to do something non-web, non-device based. My first experiment with it is absolutely useless but it gave me the opportunity to familiarise myself with OpenKinect, Irrlicht (3D engine) and C++. Here’s the result: The video quality is rather poor and sped [...]

NOTE: This OpenGL ES 1.1 framework isn’t maintained anymore. Check out the OpenGL ES 2.0 Rajawali framework which also supports live wallpapers. Here’s something I just added to Min3D: fog. Just a few lines of code are needed: scene.fogColor(new Color4(0, 0, 0, 255) ); scene.fogNear(10); scene.fogFar(40); scene.fogEnabled(true); You can download the .apk containing all the examples [...]

NOTE: This OpenGL ES 1.1 framework isn’t maintained anymore. Check out the OpenGL ES 2.0 Rajawali framework which also supports live wallpapers. This was a request from a Min3D user. It’s a short tutorial about how to load multiple animated MD2 files with Min3D. If you don’t know what MD2 files are, then read this. The [...]

NOTE: This OpenGL ES 1.1 framework isn’t maintained anymore. Check out the OpenGL ES 2.0 Rajawali framework which also supports live wallpapers. I’ve justed committed a new class to the Min3D repository on Google Code: SkyBox. Here’s how to use it: public void initScene() { /** * Create a new Skybox. The first parameter specifies the [...]

I made this one for an internal presentation about WebGL. I did the presentation but for some reason I used plain old powerpoint slides. Don’t ask. It’s made with GLGE, JSTweener and the Blender to WebGL Exporter. I guess it could use a bit of optimisation here and there. Oh, and I have tested it [...]

Now here’s something that’s been done a thousand times before in a thousand different ways! Sometimes it’s good to re-invent the wheel so you can learn something new My purpose for this demo was to experiment with vertex and fragment shaders. They’re very powerful tools that allow you to create the most amazing effects. Click [...]

In my previous post about X3DOM I covered some of the very basics. I used a <Box> object and slapped a Twitter avatar on it. In this post I’m going to use the <IndexedFaceSet> element to create geometry dynamically. Read them pixels For this example I’ve used a PHP-script that loads an image, resizes it [...]
