Custom RViz Overlays

Why This Matters

RViz is most useful when it shows the state operators and developers actually need. Custom overlays can surface mission state, diagnostics, or spatial annotations that the stock displays do not expose well enough.

Distilled Takeaways

• Custom overlays are worthwhile when they improve operator understanding or debugging speed.
• Good overlays emphasize actionable state rather than visual novelty.
• Visualization should stay consistent with the underlying data model.
• Extra displays are only useful if they reduce ambiguity during operations.

Practical Guidance

• Add overlays for states that operators repeatedly need to infer indirectly.
• Keep text, color, and layout legible under real operating conditions.
• Validate overlays with the people who will actually use them.
• Avoid turning RViz into a dashboard full of redundant signals.
