Summary
Render archived fieldcompare diff VTK files as PNG images when result comparison fails.
Generate one image per numeric point field using distinct sphere glyphs and a generic automatically selected view.
Store images under
diff-results/visualizations/in the system-test artifacts.Keep visualization best-effort so rendering errors do not hide the original fieldcompare failure.
Fixes #441.
Test plan
Generated PNGs from synthetic scalar and vector VTK fields.
Verified the
archive-to-visualizationfailure path locally.Rendered five real
CI diff VTK files, producing 13 PNGs.Checked zero and non-zero differences visually.
Ran
pre-commitchecks successfully.
