Course: Pixar in a Box>Unit 10

Lesson 2: Mathematics of animation curves

Start here!

Overview of this lesson

Ready to dive into some math?

In this lesson we are going to uncover a really useful way to construct Bezier curves of various degrees using de Casteljau's algorithm.
We'll begin by reviewing how to do linear interpolation using the slope intercept form of a line.
Then we'll revisit de Castlejau's algorithm using the three points that were covered in the Environment modeling topic.
Finally we'll extend this construction to cubic curves which are used in animation at Pixar. We'll even see how it works for curves of any degree.

• is seventh grade too young to start learning this? just wondering.
• heck no! i have an account on several different sites, dabbling in wikipedia, scratch (scratch is why i´m taking this course) and several writing sites! (while i´m at it, does anyone know a good writing website?? i´ve found 2 but neither are very good)
• Oh no... Am I gonna pass? I am kinda horrible at math like this! Probably cause I'm a fifth grader. :V
• I'm an 8th grader and I'm not that good at math! No need to worry
• Wow i love it but dont get it relly ? im n 3 grade my kaitlyn name
• I love this because I like anime.So I want to create anime.
• How long does it take to make an {cartoon} movie?
• **a
It depends. A action movie would take some time. If you are just practicing -like the ball, just under an hour.
• I personally am not very good at math, is there a way around the math part? If not, then I will just try and learn it.
• Ready to dive into some math?
• I agree with Sofiya. You can never be too young or to old to do anything.
