Trunk now renders line dataset without color texturing. #2724

Open aowen87 opened 5 years ago

aowen87 commented 5 years ago

This recently started happening on the trunk with line datasets with nodal data. 1. Open attached dataset.2. Make a Pseudocolor plot of airVf.3. Change color table to hot_desaturated and make the line width 8.4. Draw the plot. The line will use colors that are interpolated through color space instead of using 1D textures to make a better picture. I find that when I disable the avtPolylineCleanupFilter in the Pseudocolor plot that the textures are used again and the plot looks nice. Something about the polyline cleanup filter is breaking texturing.

I think this can be closed. The ticket mentions seeing this on trunk for 2.10.0, so I ran it with VisIt 2.9.2, 2.10.3 and current develop (3.2.0) and the images all look the same to me.

I also tried disabling avtPolylineCleanupFilter in Pseudocolor plot on develop and didn't see any differences.

@BradWhitlock any comments? Can it be closed?

From 2.9.2: VisIt_2 9 2_bug2724 From 2.10.3: VisIt_2 10 3_bug2724 From develop (3.2.0) VisIt_develop_bug2724
