[Paraview] [EXTERNAL] Alpha compositing reverses the depth of objects

[Scott, W Alan]

GGrrr - that looks like a bug to me.  I replicated this bug with Wavelet/ Contour, remote server, on current master.  Want me to write up a bug, or do you want to do it?

Thanks for reporting this bug.

Subject: [EXTERNAL] [Paraview] Alpha compositing reverses the depth of objects

Hi all,

I'm having a weird problem with paraview (I'm using 4.01 for the Mac). Basically, if have an object with multiple layers, turning on transparency reverses the depth of the layers. This is easier to show than describe:

Here I have a scene constructed using the contour filter with alpha = 1.00:
[cid:image001.png at 01CEC8CD.48685110]

This is the same scene with alpha = 0.99:
[cid:image002.png at 01CEC8CD.48685110]

Several of the layers which where hidden in the back are now in front. In addition, several layers have completely transparent "windows" in them, even though the layers should just barely be transparent.

Any suggestions on how to fix/workaround this issue?

Thanks,
Christopher
