1.10. Optimizations

Significant optimizations have been added since the initial 2.0 release in order to speed up computation and rendering.

The original SGI NURBS implementation has been replaced with FEI technology and offers significant advantages:

Particular effort has been made to provide additional features that are helpful for applications that deal with large amounts of data.

Chapter 30, Optimizing Applications , deals with this topic.

OpenGL 1.1, 1.2, 1.3, 1.4, 1.5, 2.0, and 2.1 provide progressively more advanced rendering capabilities. Open Inventor version 2.2 and subsequent releases have used these versions of OpenGL on all platforms where they were available. Of course, for other platforms, OpenGL 1.0 is still supported. The main OpenGL 1.1, 1.2, 1.3, 1.4, 1.5, 2.0, and 2.1 features used are:
