[Paraview] python changes 4.0/4.1 to 4.3?

Tue Jun 9 14:40:16 EDT 2015

There is no error, just instead of the requested colours:

DataRepresentation2.DiffuseColor = [ 1, 0, 1 ]        <- purple
DataRepresentation3.DiffuseColor = [1.0, 1.0, 0.0] <- yellow
DataRepresentation4.DiffuseColor = [0.0, 1.0, 0.5] <- greenish

I get red and blue.

The colours I had with pv 4.0/4.1 can be seen here:
 http://eis.bris.ac.uk/~mexas/cgpack/201502res/cr.png
 http://eis.bris.ac.uk/~mexas/cgpack/201503res/gb.png

The colours I'm getting now with 4.3 (with the same script)
can be seen here:
 http://eis.bris.ac.uk/~mexas/cgpack/201506res/cr.png
 http://eis.bris.ac.uk/~mexas/cgpack/201506res/gb.png

The 2 data files I used are:
 http://eis.bris.ac.uk/~mexas/zg0.raw
 http://eis.bris.ac.uk/~mexas/zf5.raw

The files are raw binary, 40MB each.

I might have done something really stupid,
in which case I apologise for wasting your time.

Thanks for your help

Anton
