Tadaa! G jumps off a tree

Like a muppet, I again added more than one complication with my next attempt at animation. I’ve kept the PitchiPoy Rigify script, but spent some time bulking my figure model up to match the older child, and adjusting the rigging and edge loops for improved deformation (I think it’s improved, although it’s certainly not 100%).

Bald figfure standing on a logThe biggest new feature, though, is: HAIR! My subject was not impressed that she’s still bald, so I thought I’d just quickly build a simple, non-deforming “hat” of hair.

What I quickly did was to get frustrated with my attempts to build hair, and out of curiosity turned to tutorials on creating locks of hair with B├ęzier curves. Kent Trammell has a good CGCookie tutorial up on YouTube that has everything you need. I spent far too much time for the result, but certainly learned from the experience!

Another detail I couldn’t help adding was some “soft-body” physics simulation for the ponytail. At this point it’s rudimentary.

I felt as though my animation learning curve plateaued a bit on this one; I thought it would be an easy clip to bash out because so much of it is just arm rotations, but that motion had a lot of subtle individual motions in it that I couldn’t help chasing, and they really need more polish to really get across.

Now I know how to pin a jellylike ponytail on a donkey, though (even if I haven’t quite got the parameters tuned on the soft-body modifier).

I’ve made some notes on the animation workflow, over at chrisnicoll.net.

Second animation in Blender

Posted on

I have a video of the kids doing some interpretive dance to The Fox, and it’s packed with comedy gold. It also has a lot of variation in movements, good to study. Here’s an artist’s interpretation of how a few seconds of that went.

This time I corrected one of the errors I made in my first animation attempt: I chose a much shorter sequence to animate. I made plenty of new misjudgments to counter that, though. I should have thrown together a character mesh and let it deform however it wanted to; instead I let myself get distracted in trying to understand the flow of edges. With moderate success.

I also spent some time putting the action in a room with a TV and other objects, and making lamps. I’d planned to leave the couch as a rectangular prism, but this was annoying one of my kids. I should have told her to be happy she has a real couch to jump off of in real life and to leave my virtual boxcouch alone. But instead, I modelled a couch. Luckily for me, she isn’t feeling claustrophobic about that windowless room. Windows and curtains are not on my immediate list of things to practice in Blender.

After all that I was able to get down to work moving the character around. I don’t know if I really convincingly captured the near-miss with the desktop, but it makes me laugh, so I’m reasonably happy. Yes, the toes are still poking into the floor occasionally. Just imagine there’s a carpet there, with a really high pile.

I wrote a little more about the rigging, specifically the foot controls in the PitchiPoy version of the Rigify script.


Trying out animation

Following on from my previous ruminations on animated movies…

Looking at the armies of animators, riggers, character modellers, etc., in the credits of a major animated film, it’s evident that there’s a lot of work going into it.

Consider also the graphic novel medium, which has taken off incredibly since The Dark Knight Returns by Frank Miller, Klaus Janson and Lynn Varley flipped a switch in the 1980s. There are high-production-value books, like Dark Knight, Jeff Smith’s Bone (which is accurately labeled an epic, but which can technically be combined into one paperback), and more recently the Amulet series by Kazu Kibuishi, all of which encompass untold gruelling hours of writing, designing, drawing and redrawing, and colouring. (Bone, now available in colour, was originally in black and white but with virtuosic pencilling and inking). Telling a story in beautiful pictures takes sweat and tears, or time, headaches, and repetitive strain injury.

But there’s a lot that can be done with fewer resources and a cruder visual shorthand. Peppa Pig has cracked me up on multiple occasions, I’m not ashamed to admit. (I think I like that one better than my kids do.)

Some of the most effective cartoon art I’ve experienced belongs to Allie Brosh’s Hyperbole and a Half.

Simple, childlike drawings don’t hurt Captain Underpants’ popularity, or Wimpy Kid’s, although the attraction is different. I’m not putting down Dog Man as a work, but I don’t think it takes as long to draw as Amulet.

So high production values are not indispensable for compelling storytelling. Is there something satisfying I can produce for my own amusement with free tools and limited time? The way to find out is to simplify down to bare bones. Going back to those credits lists, the sky is obviously the limit as to how much work can be put into an animation.

To experience a little of what it’s like to animate a character, I tried really hard to simplify. I’m not good at that. I used Blender, because it’s extremely capable, but also because I have some familiarity with its interface. Blender’s dangerous, of course, because you can get fancy.

I started with a character with disconnected body parts, no fingers, no facial expressions, no hair, and no clothes. The background is ground and sky. The aim was just to copy the motion in a short clip of my older kid goofing around in the early falling snow. I didn’t add the snow!

Figuring out which parts to pose first to get the best motion was hard; I started with the feet in this case because their whimsical movements led everything else and it was all irregular. Seven seconds of this was biting off a bit more than I could comfortably chew! Maybe I should have started with a walk cycle.

The learning curve here was steep and many hours went into the posing (over a few months), with several redos. After keyframing a lot of poses, I did some cleaning up in the F-curve editor, but left it fairly rough. There’s plenty I can see to fix, especially the timing of the jump relative to the push-off from the foot. And that moment where the feet collide, due to my messing with the motion curves after keyframing. Nevermind. Time to move on to the next exercise!
