If you’re any kind of graphics geek, you’re probably familiar with the outstanding YouTube channel, Two Minute Papers. If not, you’re in for a treat! In this series, Károly Zsolnai-Fehér picks papers from the latest computer graphics and vision conferences, edits their videos and adds commentary and context to highlight the most interesting bits of the research. But what really makes the series great is his delivery: he is so genuinely excited about the fast pace of graphics research, it’s pretty much impossible to come away without catching some of that excitement yourself.
What an honor to have that firehose of enthusiasm pointed at our work for two minutes!
Maybe this should have been obvious, but it took me totally by surprise: rainbows are made entirely of polarized light! (I’m guessing this is because of how the light bounces off the insides of the raindrops on its way back to you.) So if you put on polarized lenses (like some sunglasses) and tilt your head sideways, you can make them disappear— or make them look twice as bright against the non-polarized sky!
In the 1990’s, it was typical for production companies to start their demo reels with a clock-wipe countdown. Some companies would use this as an opportunity to say something about their style, and do custom animation. (Will Vinton Studios, I remember, had a particularly cool stop-motion countdown at that time.) I thought it would be cool for Xaos to have a countdown that reflected our particular style of work, so I created this drippy ink effect counting down from 10 to 1, and a drippy version of the Xaos logo, which we put at the beginning and end of our demo reel respectively.
Some time after this, our producer got a call from MTV. They had this show called “Top 20 Video Countdown”. They wanted to use this effect for the bumpers and interstitials. Could we add the numbers 11 through 20? Our producer said “of course”, and charged them a lot of money. But it didn’t really take me that long.
Here is my first short film. I made this at PDI in 1995, during a gap between commercials. I modeled and rigged the characters, did most of the animation, and developed the wobbly ink-line look.
The pigeons’ torso was a metaball surface driven by a series of spheres along a spline between the head and the body, which were both separate IK joints (so I could easily get that pigeon-head movement style without counteranimating.) The eyes, beak, legs and wings were separate objects, each of which got rendered in its own separate pass. Each layer had its vector outline traced (using a tool originally written for scanning corporate photostats for flying logos!) I processed the curves using a procedural scripting language to give them some physics and personality, and then rendered them as black ink lines with varying thickness (using a tool written by Drew Olbrich). Finally, I ran the rendered lines through some image processing filters to get the edge darkening effect, and did some iterated stochastic silhouette dilation to add random ink blotches where the lines were thickest. Simple, really! ;-)
Here’s a cool making-of video about the design event I spoke at this past summer in Madrid. It was such a great experience. The organizers made a point of creating opportunities for the participants to really get to know each other, in keeping with the event’s theme of “connection”. I learned a lot, had tons of fun, and made some great new friends from halfway around the world. If you ever get the chance to go to this conference, don’t hesitate, just do it!
