<div class="gmail_extra">Hi Li,</div><div class="gmail_extra"><br></div><div class="gmail_extra">Looks like you may want to set the projection matrix with the intrinsic values. The pv / vtkCamera does not provide an API to do that but there is nothing stopping you from exposing it in your copy of the source. </div>

know that setting camera position, view-up direction and focal point,

stuck at setting the intrinsics: for example my camera center is not at
the image center, therefore, by just setting up the extrinsics does not
give me the correct rendering view I need.<br>
