making a video from single frames

Posted by Nikolaus Gradwohl Tue, 12 Jan 2010 10:33:15 GMT

if you have exported a directory full of single frames from a processing sketch or a tool like toonloop or gimp you can combine them to a video using mencoder like this.

mencoder "mf://*.jpg" -mf fps=12 -o output.avi -ovc lavc -lavcopts vcodec=mpeg

the mplayer manual has more details in case you need them

here is a sample video i made using toonloop and some colored buildingblocks

Deploying Processing apps using WebStart

Posted by Nikolaus Gradwohl Mon, 11 Jan 2010 10:22:22 GMT

To deploy a processing sketch via java webstart export the sketch as an application (i used my randomlines sketch and exported it as a linux application).

then i wrote a simple jnlp file and copied the files to my webserver. The only thing thats left is providing a link to the jnlp file like this.

click here to dowload and launch the application

More info on jnlp and webstart can be found here

test.jnlp

Smiley-O-Mat

Posted by Nikolaus Gradwohl Fri, 08 Jan 2010 04:20:23 GMT

I just finished my Smiley-O-Mat - it's a tin-box with 3 turning knobs that allows you to controll the appearence of a smiley. With 3 simple turns I can now tell your co-workers, familymembers, ... how you feel at the moment and if it is wise to talk to me right now :-)

The controllerbox is made with an arduino, the smiley generator is written in processing, and the turning knobs are printed on my makerbot

This is what the controller looks like controler box

and here are some smileys i generated

Floating Processing cloudes with minim

Posted by Nikolaus Gradwohl Mon, 04 Jan 2010 02:59:54 GMT

I made a simple example to test the sound input features of minim, an audio library for processing.

I took one of the cloudes i wrote for my ical-flowers and wrote a simple sketch that makes it float to the right whenever someone blows into the microphone.
