# Character modeling

Contents

To get Pixar characters to not look so “computer-y,” artists turn to modeling, creating virtual 3-D shapes on the computer. To smooth those shapes out and make them look even more real, they use a simple algorithm called “subdivision,” and you’ll get to try it, too.

Discover one of Pixar's key modeling technologies: subdivision surfaces. This lesson introduces the split and average operations used to make smooth surfaces. It takes 40-50 minutes to complete.

Explore how to calculate a weighted average of three points and connect this to the subdivision operation from lesson Lesson One. This lesson takes 35-50 minutes to complete.
