Camera information inconsistent

[Nicholas Yue]

Hi

	I was trying to set up a camera view using values I obtain in a "proc"
call.

	I find that the values printed did not reproduce the same figure.

	Any idea ?


[SNIP]

set cam1 [ren1 GetActiveCamera]
	$cam1 SetViewUp -0.220679 -0.502572 0.835896 
	$cam1 SetFocalPoint 0.179291 0.277351 -0.0254646 
	$cam1 SetPosition 0.796565 0.948705 0.541141 
	$cam1 SetViewAngle 45

[SNIP]

eval plane SetExtent 0 0 0 32 0 160
renWin Render

# prevent the tk window from showing up then start the event loop
wm withdraw .

proc Pick {cam1} {
    puts [$cam1 GetViewUp]
    puts [$cam1 GetFocalPoint]
    puts [$cam1 GetPosition]
    puts [$cam1 GetViewAngle]
}

iren SetEndPickMethod  {Pick $cam1}

Cheers
