This is so cool, I’m glad the company allowed the author to release this to the public. People like myself with knowledge of some of the art and technology involved but that stand outside the industry can get a little bit of a sense how the SOTA of animation evolves.

Secondly the bit about the evolution catching the unnamed studio, likely Pixar in production capability as of the first Zootopia certainly shows up on screen.

What I like about this piece is how it shows the technical prowess underpinning the visual outputs in a film like what Disney puts out.

I only wish it went further! There are a ton of lessons those of us outside films/games could learn from working in that kind of deadline-consttrained innovative landscape. Tell about how you fought against the rendering deadlines and sped up the snowscape frames by 30% to get it in under the wire!

There have been quite a few publications about Disney's renderer called 'Hyperion', for instance https://dl.acm.org/doi/epdf/10.1145/3182159

Hi! Author of the original post here. Please see:

Hair, water, and wind - its crazy how those elements are the things that continue to have levels of improvement for these animated films yet for my eyes i keep thinking "well thats looks pretty solid to me" only to be outdone by the next movie and go "oh yeah that looks better somehow".

I totally agree. I love watching a small set of animated films over the holidays in time order to really see the technical progress. It's especially fun to go from something nostalgic I loved as a kid, to something I can really see the technical underpinnings of today.

Learning about these improvements gives incredible respect and appreciation for our eyes evolved over millennia.

Very interesting and so many throwaway lines that could easily be entire blog posts by themselves!

I wonder how hamstrung Disney is by their chosen animation style (wide-eyed cutesy characters, rounded edges, bright colours). Given the technical prowess on display here, what could they create if they gave their artists free rein to experiment like in Love, Death, and Robots? Or is it more that these constraints provide structure to work inside?

People are already working for years on Zootopia 2 and every one of their technolical advances were driven by that movie.

These inventions are represented at Siggraph and are often also research paper and land in the whole ecosystem (in software like hudini).

LDR live from their ideas and stories and experiments with styles. I don't think its relevant for technology it would just be a tech demo.

Always love it when a company can have strong technical chops even when their main product/industry isn't necessarily the tech itself.
Fazebooking•36m ago
I always say "most companies today are IT companies, they just don't know it".

I would argue that Disney is definitily a big IT company and relies a lot on that tech.

Perfect storytelling might need flaweless execution to not distract. cirque du soleil for example are also experts in every single aspect relevant to their show/business. Check out the YT video from their sound manager " Inside the Sound of Cirque du Soleil: Drawn to Life" this is so crazy but it explains so much especially how they control the audiance clapping.

Yes, when people talk down on big corporations, it is stuff like this that gives me hope and I wish people could give them more credit for what they give back to society. People always ask "where is the modern Bell Labs" and I think the answer is simple: all around us.
