[vtkusers] Re: Scalar color / LookupTable / Interpolation problem...

[Steve Joyce]

Hi,

We would like a solution for this as well for colouring finite element
models.
We briefly looked at using some of the contouring classes, but couldn't
get them to work the way we wanted. I would be very interested in any
solutions that are proposed.
A more controllable legend class would be nice too.

Yes, it seems so...

Yes, right.. That is the problem!

BUT.. there must be a solution on that one! Are we the only
one needing this ? ;)
And it defintively works in plain OpenGL! I am re-writing
our plain OpenGL to VTK...
See the attached picture. We cannot use it the way it is... :(

Yes, please. Thanks a lot !!
