Introducing the Worm Blob

Our next task is to create a worm blob which requires us to look at pose to pose and forward animation. For the worm blob we need to think of the emotional response we want to portray through the worm and how the objects play a part in the scene.

Pose to Pose & Forward Animation

There are two approaches to animation, pose to pose animation is about planning the main poses of the animation which are required to set the scene. In this approach more time is spent on improving key drawing which gives more control. This is different to forward animation (otherwise known as straight ahead) takes forward from one drawing to the next and creates more spontaneous animations.

Usually both approach are combined, using the pose to pose as a  guide and using forward animation to fill the gaps in between. However it also depends on what is happening to determine what approach to use.

“Another element that should be considered in choosing the method of animation is texture. A series of action all with the same intensity and amount of movement will quickly become tedious and predictable. It will have no punch. But if the overall pattern contains accents  and surprises…the whole thing becomes a delight to watch.” – Illusion of Life

Alan Becker describes both of these approaches

Straight Ahead & Pose to Pose Video

An example below of both methods seeing how straight ahead creates a more spontaneous animation where as the pose to pose has greater control.

Slow In and Out

This principle is crucial for achieving a life alike animation. Slow in and out shows movement starting slowly and builds momentum then slowing out. However used incorrectly can leave the animation feeling mechanical. By inserting an in-between poses and setting key frames to the extremes of each sides you can create a more fluent animation.

In 3D Animation, changing the slow in and out is changing the animation from stepped to spline. On digital tutor, they give an insight into stepped and splined animation

“With either method that you choose you should still have planning in place. Even if you block your animation in spline you need to have an idea of what it is you’re going to animate. While blocking in spline allows you to work very quickly it doesn’t mean you should forget everything you know about properly planning an animation.”- Digital Tutor

In relation to to the worm blob and when he moves we should think about the speed and which . As the worm is rigged, his tail and head move differently so using this principle, we can effect how he moves creating a smoother animation

Here is an example of the worm blob and the process of stepped to splined

Alan Becker of course has a video to explain this principle

Slow In and Out

This link Alec shared to us also helps as a way of understanding slow in and out in animation

Looking at the character of the worm blob as it is a simple shape requires us think of how we could animate emotions. This picture Alec shared made it useful to visual emotions in simple shapes
