Brian Hayes, a writer for American Scientist, delivered one of three lectures about Russian mathematician Andrey A. Markov on Wednesday. The session at the Maxwell-Dworkin building, “100 Years of Markov Chains,” was the first of three symposia this week in ComputeFest 2013, sponsored by the Harvard School of Engineering and Applied Sciences.

A team of computer graphics experts at Harvard developed a software tool that achieves two things: It identifies the ideal locations for the action figure’s joints, based on the character’s virtual articulation behavior, and then it optimizes the size and location of those joints for the physical world. Then the 3-D printer sets to work, and out comes a fully assembled, robust, articulated action figure, bringing the virtual world to life.
