Working with Splines
Learning Objectives
After completing this chapter, you will be able to:
• Work with spline primitives
• Understand spline modeling techniques
• Create geometries using Generators
INTRODUCTION
In computer graphics, a spline is a line formed by connecting a sequence of vertices lying
in 3D space. Although, it is formed in 3D space, it has no depth. A spline is not visible on
rendering. You can create complete parametric spline primitives (with pre-defined shapes)
as well as empty splines whose shapes can be defined interactively in the viewport. You can
use splines to create complex geometries using Generator objects in CINEMA 4D. Generat-
ors are CINEMA 4D's most powerful modeling tools.
TUTORIALS
Before you start tutorials of this chapter, you need to download the
c02_cinema4d_r16_tut.zip
file from
www.cadcim.com
. The path of the file is as follows:

R16 Studio: A Tutorial Approach
Next, you need to extract the contents of the zip file. To do so, navigate to the
Documents
folder and create a new folder in it with the name
c4dr16.
Next, you need to browse to
\Documents\c4dr16
and create a new folder in it with the name
c02
. Then, extract the con-
tents of the zip file in this folder.
