Move a Parallel Camera
-
Does appending a call to view.refresh (at the end of the code,) have any effect ??
-
No, no difference.
I did notice that when I switch back to a Perspective Camera, the camera jumps way back.
-
OK.. and what happens when you switch back to Parallel ?
-
A few other questions:
Do these have any effect?
view.invalidate()view.dynamic=true -
Neither has nay effect.
-
Maybe change to perspective mode, then move, then jump back to parallel? Or do that on a camera that is not active_view and then apply that camera to the active view?
-
Yep, thanks. I can make something work. I guess at this point I am curious to understand what's going on.

Solved.
This code works no matter what mode the camera is in, AND resets the mode back to the previous mode. (See ### bracketed statements that I added.)

You need to use camera.height in parallel mode.
