Learned Things
- "The simulation engine gets confused by accelerations that in the real world are impossible,” Travers says. “And that adds to the complexity of what we’re doing. Most of the time with fluid simulations, you plug in the numbers and 90 percent of the time right out of the gate, it explodes. You have to run a bunch of simulations to make it work.” Never knew making liquid would be so much of a pain.
- "We don’t break the physics,” Travers says, “but, if you know gravity in the real world is 9.8 meters per second squared, you don’t say, ‘I’m never going to change that co-efficient.’ Everything is fair game toward making the shot look good. So, you know you need gravity, but you have to let go of constraints and assumptions from the real world. You might set gravity at 2 or 1000 to make the simulation work. If it looks good, it is good.” Gravity science fun. Sounds like too much math to me though.
- "The simulations in this animated sci-fi comedy, presented unique challenges. First, they liquids in whatever form had to be in scale with the size of the edible characters. Milk became an ocean; syrup, a river. “When Barry the strawberry drops into the coconut milk, we needed to have that look like a strawberry in milk,” Travers says, “but Barry is 20 times bigger than a strawberry. So, we had to scale the fluid simulation up 20 times.”" So much sciency things.
Opinions
- Such math. Very think.
- Playing with gravity sounds pretty hard, but I am probably over thinking it. Maybe they just have a scale thing that they click and drag in the program or whatever.
Question
- How much time does it take to produce a full-length 3D animated film? They talk about that one 45 second shot taking 2.15 million hours of rendering time.
