Hi Neollie,<br /><br />
the ViewMatrix you can get from the camera object:
<pre> renWin->GetRenderers()->GetFirstRenderer()->GetActiveCamera()->GetViewTransformMatrix()</pre>
Just as an additional information: the projection matrix you can get with GetProjectionTransformMatrix() and the combination of view and projection matrix via GetCompositeProjectionTransformMatrix().<br /><br />
Don't know exactly what you mean by view vector, but you may think of the vector between camera's position and the focal point.<br />
This vector can be retrieved like this:
<pre> renWin->GetRenderers()->GetFirstRenderer()->GetActiveCamera()->GetDirectionOfProjection()</pre>
In case you mean camera's orientation (the pitch, yaw- and roll angle) you can get this three angles like so:
<pre> renWin->GetRenderers()->GetFirstRenderer()->GetActiveCamera()->GetOrientation()</pre>
Hopefully this information is useful.<br /><br />
with best regards<br />
Jochen
