<br>
I'm building a program that uses the externalVTKWidget to volume render an<br>
object in an OpenGL context. Right now, I'm calling<br>
<br>
*ren->GetActiveCamera();<br>
*<br>
<br>
(where ren is a vtkExternalOpenGLRenderWindow instance) in my render<br>
function so I can control the position and focal point of the camera.<br>
However, I'm unable to get the camera to actually have any effect on the<br>
scene. The documentation for vtkExternalOpenGLCamera is rather slim, and I<br>
can't find any similar examples, so I am a bit stuck on this issue.<br>
<br>
Does anyone have any insight into how I could approach this problem? Thanks<br>
in advance!<br>
<br>
Elaine<br>
