// .NAME vtkExternalOpenGLRenderer - OpenGL renderer
|
|
// .SECTION Description
|
|
// vtkExternalOpenGLRenderer is a secondary implementation of the class
|
|
// vtkOpenGLRenderer. vtkExternalOpenGLRenderer interfaces to the
|
|
// OpenGL graphics library. This class provides API to preserve the color and
|
|
// depth buffers, thereby allowing external applications to manage the OpenGL
|
|
// buffers. This becomes very useful when there are multiple OpenGL applications
|
|
// sharing the same OpenGL context.
|
|
//
|
|
// vtkExternalOpenGLRenderer makes sure that the camera used in the scene if of
|
|
// type vtkExternalOpenGLCamera. It manages light and camera transformations for
|
|
// VTK objects in the OpenGL context.
|
