Proof of concept
From Free net encyclopedia
A proof of concept is a short and/or incomplete realization (or synopsis) of a certain method or idea(s) to demonstrate its feasibility.
The proof of concept is usually considered a milestone on the way of a fully functioning prototype.
In computer security the term proof of concept (proof of concept code or PoC) is often used as a synonym for a zero-day exploit which, mainly for its early creation, does not take full advantage over some vulnerability.
In film, Sky Captain and the World of Tomorrow and Sin City used proof of concept short films to demonstrate what digital film and fully computer-generated imagery backgrounds would look like. In the case of Sin City, the proof of concept short made by director Robert Rodriguez was also used to convince Frank Miller, the author and artist of the original graphic novel series to approve the release of the movie rights. Supposedly, Rodriguez also used the proof of concept to convince the actors he wanted to cast in various parts. The proof of concept was used in the opening of the movie.
Pixar Example
The computer animation specialists Pixar sometimes create short animated films that include a proof of concept of a technically difficult task. Their short film Geri's Game (1997) included proofs of concept of the animation of cloth and of human facial expressions. These techniques were later used in the film Toy Story 2 (1999).
Similarly, in preparation for the creation of the film Finding Nemo (2003), the team created several short proofs of concept to experiment with the animation of water movement, the tentacles of a sea anemone, and the slow appearance of a whale swimming toward the camera from a long distance. These proofs of concept demonstrated ways for the team to accomplish difficult technical tasks, or proved that a particular creative concept "worked" (or didn't work).
