    I think Pixar is far superior to Dreamworks when it comes to fully animated movies. Dreamworks seems to be much better at special effects and environmentals. I think the two might be better off merging than competing in different areas.

    I personally thought that the facial expressions of the characters in Shrek and Shrek 2 were the best part of the movies. It gave it a character that most other animated films don't have (save for a few, most recently Finding Nemo).

    Shrek 2 was an amazing movie, and as a college student I and the rest of the group of ~15 people that went thourougly enjoyed it. It was funny, had an interesting story, and held our interest for almost 2 hours.

    "Of all the advances on this film, I think that our use of global illumination was the biggest technology breakthrough," asserts Bielenberg. "Ray tracing/global illumination/radiosity techniques have been out there for a number of years, but it has been price-prohibitive to utilize them significantly. For Shrek 2 we used global illumination for 80% of the shots. "It's our own renderer, and it's been re-written since the first Shrek. We developed a bounce light technique that --given a key light -- automatically computes the correct bounce light off of the other objects in the scene. If the light bounces off of a yellow wall, it will bounce back yellow in character.

      Yes, we rewrote an entire renderer :) We also use propietary software to do layout and animate characters, and our effects are about 60% propietary as well.

      PDI has been around since the early 80s, when commercial software was not really an option. Over time, we've amassed both a core of pretty cool technology and an r&d group to put it together. Face it, any project the size of Shrek will require lots of ad hoc software, and having total control over it is definitely an advantage.

      Because PDI is a mostly propietary place. They wrote their own renderer years before there was anything commercially available. As such they have an R&D team continually updating their infrastructure. Interestingly enough I saw a couple of PDI guys at the SIGGRAPH photon mapping course by Henrik Wann Jensen a few years ago in San Antonio.

      The upside is you don't have to wait for a commercial vendor to get those new features. They control their own destiny rendering wise. Witness for example how long it took Pixar to make Depp Shadow maps available in PRMan (something like 2 years) even though they had published a SIGGRAPH paper and were using it internally (for Monsters Inc.). Some clients were a bit upset about that.

      Dan Wexler used to write their renderer (he is now at Nvidia with Larry Gritz and those crazy Entropy guys). He has some interesting statistics on the first film:

    While others may agree or disagree with your analysis of the technical feats of Shrek and Shrek 2, if you're going to the movie just for the graphics, then you're really missing out.

    The two movies are huge hits not because of their graphics (although it doesn't hurt) but because of their stories.

    People in general value good stories much more than good graphics. The same can be applied to the gaming industry -- while games with amazing graphics may sell well initially, they will only last until the next eye candy comes out a few weeks later. Games with solid gameplay will continue to be played for years (see Counter Strike for an example).

    Plus, they must have been doing something right with the graphics -- I've never heard an entire audience simultaneously sigh "Awwwww" because of a cartoon before (if you've seen the movie you know what I'm talking about).

    Dreamworks and Pixar have both done very well with their CG movies, but they both have different styles and both have their own animation engines. They deserve a pat on the back for all their hard work.

    As an animation major (and a slashdotting girl) I enjoy almost all "cartoons" but I don't think the final product of CG should be ultimate realism. I like the direction Dreamworks and Pixar are taking - I call it "realism with style". If we wanted ultimate realism we could just film people, but it's the style, characters and the ability of the viewer to suspend belief that makes an animation special.

    Dreamworks and Pixar have both done excellent animations - if they're trying to be competitive I think it's all the better for us - we get twice as many good films. All I can say is that both of these companies are much better at creating sequels than Disney is.

I've been at PDI for more than seven years, and thus know tons of people working here who used to be at Pixar, and tons of people at Pixar who worked here and are my friends, and the same could be said about any of the other major cg companies.

Oh, and sometimes there's also a story that those people are trying to tell, and your water sim is one of the tools they are using, so the *need* that kind of control.

    Then there's rendering. Is there any foam? Splashes? Do things around the water get wet? Can you make that foam not *darker*, but *less bright* please? (this is a real comment I got during dailies in Shrek 2).

    Look, it is CG. It is, for many years at this rate of technology, going to look like CG if you do the entire movie in it. You can either play with it or you can look like a clown trying to ignore it.

    I think that the biggest problem with Final Fantasy was the fact that it did look animated. There was too much seriousness going on with animated characters. It just didn't sell as a human drama. It wasn't a human drama. It WAS A CG DRAMA. This is the difference between the best film you've ever seen, and being up front row with the worst play you've ever seen. The play is still more immersive.

    The movie was, in a nut shell, as well thought out as one would making Shindler's List an animated movie... or telling Frank Zappa to keep it clean, straightforward, and don't go over anyone's head. Even Mizayaki doesn't try to give a 'most realistic looking people' project. And he does animation like a master.

    Final Fantasy the movie failed because it played to all of the disadvantages, and none of the advantages of the medium. ART is never about, "toning it down."

    "Let's impress people by how real we can make it."

    NO! NO! NO! Bad idea! Comics and animated characters are loved for their elasticity and style. You just don't try to make a style that is "indistinguishable from normal." That is playing to all of the disadvantages, and none of the advantages of the medium. Good actors don't try to be "normal." They try to be extraordinary. All good art tries the same.

    If they wanted drama, good acting, and suspense, they should stick with real actors.

    If you want unreality... elasticity... uniqueness... style and art, then you go with an animated medium.

    Final Fantasy was shortsighted. They thought the cutscenes in the game could be a movie. It is like saying, "let's remake the Godfather movies, but use CG instead of actors! Make it real serious! That'll show this CG is a serious medium!"

But now we have this other underwater movie, which seems an awful lot like it was inspired by Finding Nemo.. but with massive cash thrown at voice talent (check it out) and dumber-looking sharks.
