Detailed Description

OpenGL camera.

vtkExternalOpenGLCamera is a concrete implementation of the abstract class vtkCamera. vtkExternalOpenGLCamera interfaces to the OpenGL rendering library. This class extends vtkOpenGLCamera by introducing API wherein the camera matrices can be set explicitly by the application.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkOpenGLCamera.

void vtkExternalOpenGLCamera::Render ( vtkRenderer * ren )

virtual

Implement base class method.

Reimplemented from vtkCamera.

void vtkExternalOpenGLCamera::SetViewTransformMatrix ( const double elements[16] )

Set the view transform matrix
