An oldish Processing reactive video project displays a person’s image as a set of 3d pixels.

You need a webcam to view. Instructions: Stand back from camera. Move around. Move slider to adjust block size. Turn on and off your video. Click on blocks for other presets.

View here.

Publishing a Processing Webcam Applet on the web

I had a bit of trouble working out how to get a video stream into a Processing applet, so I thought I’d give a quick rundown here in case someone else needs to know. The information is adapted from processing hacks – how to sign an applet

Export your sketch as an applet.
Open a terminal program and navigate to the applet directory where your applet is located (a subdirectory of where your sketch is located). The easiest way to do this is type “cd ” in terminal, then just drag the applet folder onto terminal, and it will automatically insert the path name.

Then type the following in terminal. But most importantly:
- replace xxx with the name of your .jar file. Repeat this process for all the .jar files. Remember to sign ALL the .jar files, ie. your applet .jar, core.jar, and video.jar files, this was the confusing part that’s not explained properly on the hacks site.
- the password you should enter when prompted is ‘Password’

keytool -genkey -keystore pKeyStore -alias radarboy
keytool -selfcert -keystore pKeyStore -alias radarboy
jarsigner -keystore pKeyStore xxx.jar radarboy


Upload your applet and voila, you have a self-signed, working web applet.
