Parallel Projection and RenderLargeImage ?

[Markus Heller]

Hi,

I'm experiencing some trouble combining a camera
with parallel projection and vtkRenderLargeImage.

I've got something in Tcl like:

set cam1 [ren1 GetActiveCamera]

If I set:

$cam1 ParallelProjectionOn

the subsequent code:

vtkRenderLargeImage renderLarge
  renderLarge SetInput ren1
  renderLarge SetMagnification 5

does not work. If I leave out the line
"$cam1 ParallelProjectionOn", I get a
perspective projection and vtkRenderLargeImage
works fine. 

I guess the problem is that magnification
is handled different for parallel/perspective
projection ???
