Modeling an avalanche

Last week I posted a video from Jeremy White, loosely describing how he turned LIDAR data into a stunning model of Tunnel Creek. But more modeling yet went into showing exactly where the avalanche happened and how it traveled. My colleague Graham Roberts added trees, elevation lines and an actual model of the avalanche – its shape, depth, and size — as it flowed down the mountain. (The Swiss Federal Institute for Snow and Avalanche Research created the model specifically for this project.)

Below, a set of drafts that show the animation at various points along completion. These are courtesy of Graham, who rendered these in 3D, and Hannah Fairfield, one of the project’s editors.

Contrast these to the version that made it into the project (I failed at internet in trying to post that video here, but it looks better on the Snow Fall page anyway). You’ll see that they added elevation lines, toned back the background sound a bit and added a faint “tick” to help show the speed of the avalanche as it moved down the mountain.

Sketches from One Race, Every Medalist Ever

One of our most recognizable Olympics graphics is probably “One Race, every Medalist Ever,” a 3D rendering and video that imagines what a race of every athlete ever to medal in the men’s 100-meter sprint might look like.

I’d love to take credit for the idea, but it’s not new. The first time I ever saw the idea was in 2009, when my colleague Bill Marsh had a small piece in the Week in Review after Usain Bolt got a 9.58 in Berlin, setting the world record that still stands.

Even this year, other news organizations did a similar approach. The Guardian made one in a retro homage to old video games and Slate had a piece based on the same concept. But one reason I think ours was so successful is that is put the race on a human scale – seeing all those athletes on an actual track is much more accessible than seeing a scatterplot. (Not that I didn’t make tons of scatterplots since they don’t really let me near the 3D software.)

So Graham Roberts started rendering some people on a track based on some initial calculations. Even his first renderings looked pretty cool:

After that, it was just a (very slow) process of storyboarding the video. It’s surprising, to me, anyway, how much the final movie tracked our original storyboard:

Then it was just a matter of rendering all the frames, recording and syncing the audio, and thinking about how to turn it around as soon as possible after the result. If you look closely, you can see that the 2012 results are out of frame for most of the movie – it was mostly pre-rendered. (We also recorded slightly different scripts depending on who won. I didn’t really care who won, but I was sort of rooting against Churandy Martina of the Netherlands because I couldn’t pronounce his name right. Luckily for me, he got sixth.) 

We didn’t end up turning it around as fast as we wanted to, but about 8 hours after Bolt had won the 100-meter final, the piece was up, and only a day or two later Graham and I had achieved a life goal of having Ashton Kutcher tweet our work.

We also did a chart for print, which went across two pages. Although we had done the chart in perspective for swimming (I’ll get to that another time), the side view of these guys looked really cool, with Usain Bolt leading and everyone in history trailing behind. It was even cooler in the 2008 view, actually:

And in print on Monday, Aug. 6:

I have a couple other fun things from this piece, but I’ll save those for another day. (Like maybe tomorrow.)

The Olympics Are Almost Over!

Closing ceremonies are this weekend, which means the Olympics are almost over.

As many readers/skimmers/aggregators of Chartsnthings might know, the New York Times graphics department published one or two things about the Olympics recently, and I’ll try to post little tidbits where I can instead of making a few massive posts.

What better place to start than in the Olympic pool, where we last left our flags on our Speedos? (Sorry about that one.)

Making mistakes outside the chart

Part of this blog is intended to show the processes behind our work, including bad ideas. (Especially bad ideas.) But screw-ups don’t happen just in charts. For example, here’s a recent, not-really-verbatim conversation I had with my colleague Graham Roberts as we looked at visualizing swimmers for an upcoming Olympics project:

GR: “We need a decent way to identify these guys.”

KQ: “What if we put a flag on their bathing suits?”

GR: “Like on their Speedos? Wouldn’t that be weird?”

KQ: “Not really.”

GR: “Really?”

KQ: “Let’s just see what it looks like.”

[5 minutes later]

Flag butt

KQ: “So, no flags, huh.”

GR: “Yeah.”
