jumping ball with overlapping tail motion

My hand-drawn 2D interpretation of the fourth Animation Mentor assignment.



I've committed a classic art school student mistake here... making the assignment more complicated than it needed to be. The actual assigned task was just to animate the ball doing three jumps with overlapping motion on the trailing tail, all from a straight side view.

Trying to draw this from an angle made this mega harder. In CG the computer handles perspective and character size and volume for you automatically. In 2D that's a battle you fight on every frame.

The falling block was an off-topic addition too. If you watch it it does a nice little bounce as it hits the ground, but if you're watching the block you're not watching the ball and tail, which was the real object of the assignment.

Drawing that solid block in perspective as it tips over was a time-eating challenge, and I could have gotten a better result, faster by animating it in 3D (with Animation:Master, of course) and rotoscoping that into my drawings. Which I will do in the future if I need any tumbling solids.

I'll give myself a passing grade on this. I don't think this would be "A" work but I think it shows successful overlapping motion.

why mickey wears shorts

As I was trying to draw some legs on a simple character it occurred to me that putting Mickey mouse in shorts wasn't just for modesty's sake.

If you look at a typical flat-colored rubber-hose style appendage as in "a" it's rather ambiguous as to which way it is really bending.



But if you add that pant cuff just a little bit down the leg as in "b" or "c" you get a clue as to the intended direction of the knee.

Of course, there are lots of times that Mickey doesn't wear shorts, but then they have to work harder at drawing him with real articulated knees.

vertical jump test

This is really just a preparatory study for a more complicated exercise I'm working on, so I didn't spend any time doing cleanup on it. I'm working on a character jumping forward and I did this to simplify it down to just the up and down motion.

obstacle course with anticipation

A squetchy ball jumping (with anticipation) thru an irregular obstacle course. My 2D re-make of the third AnimationMentor assignment.





Includes a brief bit of "drybrush" motion blur drawn onto the frames with ArtRage Studio's "crayon" brush.

Rigorous physics simulation has taken a back seat here to trying to get the overall flow right. Some these bounces are weightier than others.

This is mostly two's with some brief one's. Not all of the bounces are full Preston Blair-style bounces; they seemed to be killing the momentum of the ball in spots.

damped pendulum started with a hook

A brief exercise in oscillating motion and slowly coming to a stop. This is all on twos except for the very last swing which was just too small to inbetween so it has a couple of fours in it.

red balloon, lead balloon

My hand-drawn, 2D interpretation of the second Animation Mentor exercise: the light ball, heavy ball test.



My goal was to make the light ball so light that air resistance is a major factor in its motion.

This is animated on ones, twos, threes and even some fours and fives. One surprising discovery was that more inbetweens did not necessarily make the light ball look smoother or lighter.

I recall when I was in elementary school that every year they would show us Albert Lamorisse's "Le Ballon Rouge" (The Red Balloon), which I guess was their subtle way of teaching us it was bad to beat up on red balloons.

rotating cylinder

A rotating cylinder turning in perspective. A brief exercise in trying to be accurate.

I used the usual vector drawing tools to make smooth lines but no 3D modeling is involved here. The rotating box on the upper right is an "overhead" view to help me guesstimate the changing profile of the cylinder as it turned.

Pretty close.

swishy cow tail

Twenty years ago I tried to draw something like this in Deluxe Paint on my AMIGA computer, but the overlapping motion was too much to wrap my mind around. So this is progress, right?

with every christmas card I blight

I don't send out actual Christmas cards anymore, but when I send someone a gift I sketch out some quick personalized scribble to attach to it.

Here are a few I cranked out today with the ulterior motive of practicing my generic cartoon character construction:

for my nephew who wants to be a pilot


for my niece who has started learning clarinet




a Boxing Day card for one of my non-Christmas celebrating friends

bouncing ball 2

Ok, here's some actual new animation. The squetchy bouncing ball. I did this all on "twos" (two frames per drawing at 24 frames per second) just to see how that would look. The contact frames look a bit sticky on two's but I think it works.



The strobing isn't as bad as I expected. To investigate that a bit further I did this little turn test on a cone. One is on ones and the other is on twos. Can you tell which is which?



Not a dramatic difference, is it?
