Wavelet constant color or colormap

[aronhelser]

• Use the '+' to add a Wavelet source
• Change to a Volume view
• Change from 'Solid color' to '(p1) RTData'
• Use the gear icon to change colormaps - choose one of the first two, solid purple or solid green Bug: no change to wavelet display. Is a solid color valid for a wavelet? Notice that the wavelet also displays nothing when first changed to Volume view - is 'solid color' valid?

In addition:

• Use the bookmark icon to display the color scale bar. Bug: for a single color colormap nothing displays. For other colormaps a valid scale bar displays.

I was able to see some error messages printed if I ran Visualizer using pvpython directly, with --debug: pvpython "C:\akit\visualizer\server\pvw-visualizer.py" --content "C:\akit\visualizer\dist" --port 8080 --data "C:/akit/data" --debug 2>&1 | tee debug.txt This output is very verbose and includes binary data, so search is your friend.

I think we should add a pass-through ability, so the 'Visualizer' command can pass arguments to pvpython that it doesn't recognize.

You can not do Volume rendering on a solid color. You need a scalar for that.

OK, makes sense. In ParaView, if I add a Wavelet source, the Coloring automatically changes to RTData. Paraview also only allows you choose a color scale, rather than a solid color.

Are the solid color options added to the colormap list for simplicity? This case might point to the need for them to be separate.

I've pushed a new preset.json with the removed single color.

Looks like we got all the constant color ones. I seem to have found one other problem colormap. Green Linear (9_17f) won't color wavelets or sphere normals for me. Haven't tracked the error yet.

OK, think we've removed all the problem colormaps. Closing.
