kadoin-FaceOSC

Behind all that metal and code might there really be… a soul?

What’s happening?

  • Eyes light up as eyebrows are raised
  • Mouth shows the amplitude of the song over time
  • Music gets louder as mouth is opened almost like you/the robot is singing it

Melodramatic musings aside, I had a lot of fun with this project. It sort of just started with playing around with the sample code. I didn’t have a strong concept of what I wanted to do and it was my first time playing around with 3D so I didn’t really want to get into fancy shapes, but I could make a box move around in a space, and what do boxes look like? Robots. And what kind of space could this robot be in? Outer space. Nothing I was going to make would look super realistic, so the cartooniness of all the simple shapes worked well.

I really liked the new Star Trek movie that came out this summer, it was very reminiscent of the original series. I worked at a movie theater so I got to keep the poster, but I digress.  A Beastie Boys song blew up a fleet of robot ships, which was actually very fun to watch.

So I figured Intergalactic by the Beastie Boys would be a nice touch while also giving the mouth something to do.

Add a bit of interaction, map a few things, and bada bing bada boom, I got a fun space robot. It’s not the most conceptual thing maybe not even the most original, but it was really fun to make and I really like how it turned out. It’s pretty fun.

Since I can upload video for FaceOSC to analyze, I was thinking about making a music video type thing by putting different Star Trek clips through the program, but that would probably include a decent amount of editing to make it look nice, which I didn’t have time for. It’s still something I think I’ll do eventually, though. Maybe I’ll experiment more with light sources while I’m at it.
