[osg-users] [forum] Change the position and rotation angle of the camera

[ying song]

Hi,

I draw a box using addDrawable. Then I want to change the position and rotation 
angle of the camera  by:

viewer->getCamera()->setViewMatrix(cameraTranslationMatrix);

But actually it makes no change to the camera. The cube is still in the center 
of the screen after run the scene.

I also tried to update the frame by using the following code, but also failed:

while(!viewer->done()) 
{ 
        viewer->getCamera()->setViewMatrixAsLookAt(eye,center,up);
        viewer->frame(); 
} 


Would anyone tell me what could I do to move the camera?

Thank you!

Cheers,
Becky
