Animation Fundamentals - Moving Pendulum

 Pendulum

In pendulum animation, the key principles we need to learn are overlapping and follow-through

Rules

  1. The lubrication of each joint is the same.
  2. The weight of each joint is the same.
  3. It gradually starts moving from left to right and gradually comes to a stop

Second Practice - Moving Pendulum

If you haven't seen the stationary pendulum yet, check out this link

First Image
Now, the Root moves 15 frames to the right

Second Image
Overlapping occurs at the fastest sections of the motion

In the fastest sections, the weights at the bottom try to maintain their original position, creating overlapping motion.

Then, when it stops, where should the weights be facing?
Should they continue to follow inertia and face left, like in the Second Image?

Let's think about it, Overlapping occurred in the fastest section.

This mean that when the movement gradually slows down, the weights are still carrying that mometum and being pulled forward with force of acceleration.


Third Image
Therefore, just before the Root reaches its destination, the weights should briefly surpass the Root

As the Root comes to a stop, follow-through occurs.

From this point on, you can apply what you learned from the stationary pendulum to continue the rest of the animation.

More natural !

Adding an offset to make the weights face their original position more in between the overlapping motion at the fastest section ( Second Image ) and when the Root stops ( Third Image ) will make the animation look even more natural.

Basics of Camera Techniques : Two Shot

Image
 Two Shot Definition ● Core-Concept The two-shot is the core unit for illustrating the psychological distance and the fluid dynamics of a relationship within a single frame ● Framing There are no constraints on shot size. Whether it is a distant Long Shot (LS) establishing the spatial relationship between two figures or a tight Close-up (CU) emphasizing their shared interaction, any composition that prioritizes the presence of two subjects is classified as a "Two-Shot."

Basics of Camera Techniques : Single Shot

Image
Single shot Definition Core Concept : A shot that features only one person on screen to establish a direct, 1:1 relationship between the character and the audience. Framing : There are no constraints on shot size. Whether it is a distant Long Shot (LS) or an Extreme Close-up (ECU) of just the eyes, any composition featuring a single individual is classified as a "Single Shot." When to use A Single Shot is not chosen simply because a character is physically alone It is used when there is a specific "psychological intent" Portraying Internal States : Used when a character is lost in deep thought, experiencing confusion, or making a pivotal decision. By excluding the surrounding environment, it gives the audience the sensation of stepping inside the character’s mind. Isolation and Alienation : Even in a crowded space, framing a specific character in a single shot can visually demonstrate their exclusion or psychological disconnection from the group. Exclusivity ...

Animation Fundamentals - Stationary Pendulum

Pendulum In pendulum animation, the key principles we need to learn are overlapping action and follow-through Rules 1. The lubrication of each joint is the same. 2. The weight of each joint is the same. First Practice - Stationary Pendulum If we drop the weight from this pose, what will happen? The weight will fall sequentially and preform a pendulum motion. Now, There are some important things we need to remember Start by animating the weight closest to the first root. The period of the amplitude should remain consistent. In other words, if it takes 10 frames to swing to the right, it should take 10 frames to swing back to the left It should gradually come to a stop due to gravity the timing remains the same, but the spacing varies. If there is a diffence in the period of the amplitude, the pendulum moves to the right in 10 frames but returns to the left in 9 frames, it will appear as if the pendulum is trying to return to its original position too quickly ( ex : An antenna or an obje...
