Purpose

The module SoView2DExample is a programming example to demonstrate how to develop a new SoView2DExtension which draws its own OpenGL stuff on slices in 2D viewers.

It derives from the SoView2DExtension class and needs to be connected somewhere before a SoView2D in the Open Inventor scene graph to become active.

The programmer can handle viewer events as well as OpenGL drawings on each slice shown in a viewer. Also a definition of colors, mouse buttons and different event phases is possible.

Have a close look to the source code of the SoView2DExample project for detailed programming information.
