Using WebGL & GLSL Shaders to Create a Tunnel Effect

Posted by Dennis in 3D, WebGL 9 comments

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 [...]

X3DOM Exploration #2: Creating Geometry with IndexedFaceSet

Posted by Dennis in 3D, WebGL 5 comments

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 [...]

More WebGL Exploration: Visualising Mutual Twitter Friends with X3DOM

Posted by Dennis in 3D, WebGL 6 comments

After the WebGL BoF at Siggraph I spoke to some people from the Web3D consortium and the Fraunhofer institute. This was quite interesting. The Fraunhofer institute is working on an X3D WebGL implementation called X3DOM. Basically it means that you can set up a 3D scene as part of any HTML5 DOM tree. This should [...]
