Do you know that when producing “Cars 2″, it took, on average, 11.5 hours to render one frame?
“Cars 2″ is 106-minute long = 6′360 seconds = 152′640 frames
So, had it been one computer doing all the renders, it will take 1′755′360 hours to render the whole movie = 73′140 days = 200 years and 5 months.
So, Pixar had to deploy 12′500 cores of computing power. That reduces the minimum rendering time for the final render of the whole movie to 140 hours and 26 minutes.
And that doesn’t count the need to fix glitches, retake shots because the result was not satisfactory, experiments on camera angle and lighting, changes in motion, etc.
So, let’s multiply that by a factor of 5. We get 700+ hours to render the whole 106-minute movie. And that’s just the FINAL rendering.
There are intermediate renders, motion renders, storyboard renders… and so many other things inbetween. All using the same rendering farm, only set to different quality/detail setting.
And let us not forget the Physics Engine that applies, well, the laws of physics. Like bouncing balls. Water splashes. Wind blowing a leaf. Flag waving in the wind. Smoke going up, but slanted due to wind. And so on.
In fact generating the positions of the CGI Objects for a certain frame might take hours for the Physics Engine. And only after the positions have been ascertained, can the render job be sent to the render farm.
So, folks, creating a Good Quality 3D CGI Animated Feature Film takes a lot of time. A lot of effort. And a LOT of money.
- You need to buy all those cores
- You need to buy MEMORY for all those cores
- You need to pay electricity for all those cores and their memory
- You need to COOL all those cores
- You need to pay electricity to COOL those cores
- You need a sizable Data Center to house all those cores, and good ones don’t come cheap
- You need to hire a squad of SysAdmins to maintain the systems
- You need
to hire
a squad of Network Admins to ensure that the network does not become a bottle neck
- You need
to hire
a squad of Animators to ensure that jobs get farmed properly, and render jobs come back with acceptable result
Creating a feature-length 3D CGI Movie is a Serious IT Project.
Never underestimate the cost.
