My first papervision webcam experiment

The Papervision Workshop on Flash on the Beach this year really opened my eyes on the Papervision front. I never really made the step to start experimenting with Papervision because it’s not the most accessible thing to start with. At least that’s what I thought…

Ralph Hauwert really showed how easy Papervision can be and that you can have a scene up and running in no time. So hey, in comes a rainy weekend in London and you can see the result below.

I just wanted to do something weird with a webcam and Papervision. I’ve applied a threshold to the images I capture using the webcam. The further along the line the lower the value for the threshold gets. So you get a kind of tunnel that first only shows the very bright bits and then slowly shows everything.

And I’ve added a little rotation etc just because I can

I’ve put the source code in a zip. You will need the Papervision SWC or AS3 classes to run it. If you don’t have them, please have a look at the Papervision blog on the right side (Getting started 2.0).

Colour tracking with the webcam in Flash

Something I wanted to do for a while. Track a colour using your webcam in Flash. I draw the webcam into Bitmapadata so I can play around with it. If you take the getColorBoundsRect straight from the raw bitmapdata it will be very hard to get something useful as you just have to many single pixels and colours to analise. So I implement a little trick that makes it better to analise. First I blur the video so it smooths the colours. Then I turn it into a 8 channel image.

After that I just layer a fresh video feed that isnt distorted on top and start drawing based on the colour and position.

Enjoy! You can grab the source here if you want.
