4. Scene Graph Nodes

A node is an object that can be part of or entirely comprise a scene graph. Typically, a node

is a collection of one or more ﬁelds and methods that together perform a speciﬁc

function, for example, a csShape node encapsulates all information about the shape and

appearance of a geometry.

Cosmo 3D nodes are divided into two types:

• group—associate other nodes.

• leaf— contain rendering information.

This chapter describes nodes and node types.

These are the sections in this chapter:

•“What Is a Node” on page 56.

•“Group Nodes” on page 58.

•“Leaf Nodes” on page 57.

•“Setting the Values in Scene Graph Nodes” on page 61.
