Chapter Objectives. After reading this chapter, you'll be able to do the following:
Build scene graphs using shape, property, and group nodes
Explain how nodes inherit values in the scene graph
Describe why separator nodes are useful
Explain the advantages of shared instancing of nodes in the scene graph
Define the term path and explain why paths are needed
Set and query field values
Ignore specified fields in a node
Explain how nodes are deleted in Open Inventor
Use Inventor's runtime type-checking mechanism
This chapter illustrates how to construct scene graphs from shape, property, and group nodes. It explains general rules for traversing a scene graph, focusing on GL rendering traversal. The concepts of database actions and traversal state are introduced.
