== Building a Visualization Language (9 - 10) ==

John Resig (Firebug, jQuery) presents a talk on Processing.js, his port of Processing to Canvas.

Canvas element:

• JR hasn't tried much in terms of overlaying multiple canvases on top of one another
• Review (just a raster, not scalable graphics)
• Canvases can consume other canvases, images and videos (FF 3.1)

Processing:

• Visualization language in Java, for 2D and 3D. Built by people at MIT
• Many libraries (manipulate video, etc)
• Strictly typed, very flat API. OpenGL-like (setup(), draw())
• Primitive drawing very similar to canvas
• Tons of samples on processing.org

Processing.js:

• JR ported Processing to Processing.js
• Isn't a large part of processing its main library? Yes but only the 2D drawing bits are supported.
• How do you achieve the synchronization in the Youtube video at http://ejohn.org/apps/hero/ ? Youtube API gives constant callback
