10:05 Today’s Notes & Attendance
Welcome to Week 20 – Your new semester. You are going to graduate at the end of this semester. The weather will be warmer in 5.5 months. You’ll be free of projects and homework. You can do it – let’s make this last semester of HS worthwhile.
New Seats – I’d like to arrange for new seats but we have visitors the next couple of days so we’ll wait a little longer.
Visitors from Colchester HS today:
- Ben will get a visitor
- Mr. Bohmann will get a visitor
- Mia will get a visitor
Officially we are in the start of Q3
Projects are grades / grades are in (mostly)
SkillsUSA – begins on Wednesday with a kickoff and the first practice sessions will be Thursday and Friday – Mr. Cronin and I are really excited. Skills is a grade in Q3.

10:10 Persistence of Vision
Animation or the illusion of movement is a creative form that goes back nearly 150 years. The first know animator was French, Emile Reynaud. Emile Reynaud created a projector for moving images. People paid admission to see these early animations.
Early animation devices were more optical illusions than anything else. Interesting names like zoetrope, fantascope and thaumatrope to name a few. Most of the devices worked by moving an image around in a circle at moderate speeds with light.
Vocabulary:
Persistence of Vision – or the way our eyes and brains process images is an important part of animation and in filmmaking. Each image we see stays reflected on the retina of our eyes for a microsecond after the image disappears. Our brains are very good at filling in the gaps or the “in-betweens”.
The eye stops perceiving movement of frames at about 12 frames per second.
There are a lot of animation devices we can make ourselves with some simple supplies. Before the computer, animators used all kinds of techniques to create the illusion of movement.
A Thaumatrope is an easy illusion of movement device that we can make to illustrate the persistence of vision.

Analog:
Building one is really easy in analog form. First think of an idea. Then…

11:50 – 12:25 Squash and Stretch

Do you remember the bird we made a month or so back – we did this one together. Find that model and if you don’t have one, have it ready for Tuesday. This bird will be used for demonstrating Squash and Stretch – The first animation principle! and we’ll build out a scene to go with it.
Animation Principles – there are 12. Each week over the next twelve weeks you will demonstrate a new principle with your own animation of the principle. Animations will be due the following Monday.
Certainly! Here are the 12 Principles of Animation in list form:
- Squash and Stretch
- Anticipation
- Staging
- Straight Ahead Action and Pose to Pose
- Follow Through and Overlapping Action
- Slow In and Slow Out
- Arcs
- Secondary Action
- Timing
- Exaggeration
- Solid Drawing
- Appeal
Squash and stretch is one of the most enjoyable of the principles. A nice example in the 2D space. You can really pick up on the personality and appeal of the character.
Principle #1 Squash and Stretch
Objective: Understand and apply the Squash and Stretch principle of animation using Blender.
Rendering and Exporting:
- Render the animation as a video file (e.g., MP4). Use EEVEE
- Duration: 5 seconds (24 frames per second)
- Filename: Squash_Stretch_Lastname.mp4
Ideas:
- Animate a bouncing ball or another object: Apply Squash and Stretch considering its impact on the ground and its rebound.
- Animate a character jumping: Apply Squash and Stretch to the character’s body parts, such as their legs and arms, as they jump and land.
- Animate a cartoon character expressing emotions: Use Squash and Stretch to exaggerate facial expressions, such as surprise or anger.
Assignment is due: Monday,February 3rd
- On February 3rd we’ll look at your animation and evaluate considering factors such as timing, smoothness, and creativity
- We’ll also provide constructive feedback to each other
