Detailed Description

The SoGlobalGLContextScope can be used to automatically push and pop the current GL context, and to enable a shared global Open Inventor GL context inside of the scope.

{
  SoGlobalGLContextScope scope;
  // now the current global shared GL context is current
  // do something like offscreen rendering here...
}
// when scope gets deleted, the previously current GL context is made current again
