First we'll use the slope intercept form of a line to define each frame along a straight line.
Let's start by drawing every frame, one by one...
Connecting key poses with straight lines is called linear interpolation.
First we'll review De Casteljau's algorithm using three points. Then it's your turn to figure out how to do it with 4 points!
Using Bezier curves we can get smooth motion between keyframes.
We can use de Casteljau's algorithm to calculate curves using any number of points.
Let's breathe some life into our ball using a key animation principle: squash and stretch.
Bonus! In this video we'll connect the degree of these curves to the number of control points in the construction.
This instructional program prepares students to use artistic and technological foundations to create animated presentations for industry and entertainment. Students will develop basic drawing and design skills, learn the fundamentals and physics movement, the concept of communication to a given audience, and techniques for self-expression through a variety of animated formats. They will explore the careers and requisite skills required by animators in both entertainment and the business world.
How did Rob start out?
In this lesson students will animate a ball bouncing into the "frame," squashing against the floor and stretching as it bounces up. This lesson focuses on the first principle of animation called squash and stretch. The lesson also explores exaggeration and timing.
During this lesson, students will explore concepts related to animation while creating a moving image using ideas, subject matter, and materials of their choice by designing a functional thaumatrope.
Students will explore the contemporary technique of Pixel Art- using exaggerated pixel size to emulate the low-resolution aesthetic of Late 80’s/early 90’s video games. Using a free image-editing and animation application, student can create their own pixelized version of an everyday inanimate object and then animate their image.
We'll explain how to draw circles with code (JavaScript and ProcessingJS), and then you'll get to try it yourself in a challenge.
The role that math plays in computer animation.
In this activity, learners make a stroboscope--a spinning disk with slits around the edge that you look through. Brief but frequent glimpses of images seen through the slits lead to a surprising result, which teaches learners about vision and the human nervous system. The activity includes three short online videos: Introduction, Step-by-Step Instructions, and What's Going On. Also available: a concept map and a "Going Further" document that suggests variations on this activity.
