<DIV><FONT size=2 face=Arial>Hi,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>1d cells are not colour mapped correctly with <FONT
size=2>InterpolateScalarsBeforeMappingOn(). In the 2nd image they appear as
a black line, not the colour of the 2d cells to the left and right despite
having the same scalar values. The 1d cells are shown correctly when this switch
is off (1st image).</FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>If the 1d cell actor colour is set to white before
the colour mapping, the correct colours are shown.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>This is a problem in vtk 5.8.0 (5.4.2 also). Can
anyone suggest where to start investigating?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Thanks for your help.</FONT></DIV>
