Real time animation with Animata

I bumped into this cool open source tool Animata a few days ago. It lets you import images, define joints and bones in these images and use this skeleton to animate it. This post is a basic example of what you can do with Animata. As I am totally new to the program I could be doing some things wrong, but I already like the result 🙂

First draw some figure, and make sure the limbs are easy to separate from the body. Take a photo of it or scan it and remove the background in Photoshop or The Gimp. 

Take a photo of your drawing, remove the background in an image editor and save it as a png image

Save the image in .png format and open Animata. In the first tab you can add your image to the scene. Go to the mesh tab and put a lot of vertices on you image. Click create triangle>triangulate and you should see a lot of triangles between the vertices, click on texturize. Animata will use the vertices to warp the image into some other form (when you’ll move a joint later on).

Animata lets you define a skeleton which is used to animate the image

Now you can define joints and bones in the skeleton tab. You’ll have to attach the vertices to one of the bones. Now you can move the joints and the figure will move along! 

You can create dummy bones the length of which changes periodically to move your figure’s limbs. The video below is a summary of the process (I cut out some parts).

The really cool thing about Animata is that you can control the animation from within you own custom application by simply putting some values (x,y coordinates for the joints or the length of the bones) on a local udp port. I already have a Processing example running (by using the commands from http://originalhamsters.com/blog/2008/12/15/animata-osc/) so I’ll probably write about it in a next post.. :p
