Summary0014828: Contours, color by is crazy broken
DescriptionWhen you contour, then color by something, ParaView gets very confused. I don't know if this is one bug, or numerous. Should be fixed for 4.2.

* Linux, local server, master.
* Source/ Wavelet. Apply.
* Slice. Turn off Show Plane. Apply.
* +X
* Hide visibility of Wavelet.
* Not necessary, but Reset (X)
* Contour, by rtdata, take default, apply.

<<Bug - you can't color by rtdata>>
(Ah, this is by design, you say!)

* Restart ParaView from scratch.
* Open disk_out_ref.exo. All vars on. Apply.
* Slice. Turn off Show Plane. Apply.
* +X
* Not necessary, but Reset (X)
* Color by temp.
* Contour filter. Contour by temp. Change value range to 400. Apply.
<<Inconsistancy>> We are now contouring by temp.
<<Bug>> If you look at the Color By in the Properties tab, it doesn't show Solid Color (but should). The Color By in the top tool bar does!
* Color by "Solid Color". (Top tool bar.) (Contour goes white.)
* Color editor. Change color to black.
* Color by temp.
<<bug>> Contour stays black! You can never color by any var again, until you change the color back to white.

Alan, I confirm what you see. Here are a few more details.

- I did not get this behavior on linux: "<<Bug>> If you look at the Color By in the Properties tab, it doesn't show Solid Color (but should). The Color By in the top tool bar does! " The Solid Color option did appear in the Properties tab, so that may have been fixed by another commit

- I don't see why one should not be able to color by the contour array. That should be fixed.

- Coloring by scalar arrays appears to be broken in all representations that show line segment poly data. If you take a 3D contour through the wavelet source (default settings), change the representation to Wireframe, change the solid color to green, then color by Normals, the scalar colors are obviously modulated by the green color. That's why when you choose black as the solid color, then color by an array, you see black - black modulated with any color is black.

commit daf8c6e76ec7bb02f56dda17ce260141b7e960a5

    BUG 0014828: Keep surface color from interacting with scalar color.
    
    When using scalar coloring, if vtkScalarsToColorsPainter decided to use
    a texture for mapping the scalars to colors, we ended up with the
    surface color bleeding through the texture. This commit ensures that
    such bleeding is avoided.
    
    We don't simply use glTexEnvf (GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE,
    GL_REPLACE), since that results in the diffuse highlights being lost.
    By enabling GL_COLOR_MATERIAL and calling glColor3f(1,1,1), we follow
    the same lighting/coloring path as we would when not using the texture
    for scalar coloring.
