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.
