"Real-time rendering is in quite demand in computer
science today, and OpenSceneGraph, being one of the best 3D
graphics toolkits, is being used widely in the fields of virtual
reality, scientific visualization, visual simulation, modeling,
games, mobile applications, and so on. Although you can use the
powerful OpenSceneGraph, which is based on the low-level OpenGL
API, to implement applications that simulate different environments
in the 3D world, developing picture-perfect applications is easier
said than done.
"In this article by Rui Wang and Xuelei Qian, authors of
OpenSceneGraph 3.0: Beginner's Guide, we will learn:
* Different ways to improve rendering performance, by modifying
and sharing geometries and textures
* The dynamic paging mechanism and its utilization in handling huge
