color=#0000ff size=2>This is expected behavior in ParaView 2.6. It is
because we are z-buffer depth sorting. The correct thing to do is to draw
all items in the order of back to front. This code that implements this is
currently expected to be in ParaView 2.6.1, which should be out in a month or
so.</FONT></SPAN></DIV>

Transparent objects actually solid?<BR></FONT><BR></DIV>
<DIV></DIV>List;<BR><BR>I've come across 'odd' behaviour when objects are
transparent: An object with an alpha value <
1.0 can hide another transparent. The file below contains two cubes, blue and
green. The blue cube is visible through the green cube, but not vice versa (if
you rotate). Also, if I set the blue cube's alpha value (in the lookup table) to
0.0, it completely hides the green one, I would've expected to see the green
cube since the blue one is transparent (?)<BR><BR>The only way to get around
this is to set the opacity value to anything < 1.00 in the Object Inspector
(Display/Style), then it works, which is probably OK, but it's freaking me
out... This is for ParaView 2.6 and alpha 3.<BR><BR>Is this the intended
behaviour? If not, what gives?<BR><BR># vtk DataFile Version 2.0<BR>Really
