Screenshots

This page is a screenshot capture checklist for the Core Interactions section.

It exists so you (or a collaborator) can capture screenshots once, systematically, without hunting through every page.

How placeholders work

All pages in this section currently use:

• cellucid-python/docs/_static/screenshots/placeholder-screenshot.svg

Each placeholder is preceded by an HTML comment with:

• what state to capture,

• what to crop/redact,

• suggested caption/alt text,

• suggested filename conventions.

General guidance lives in:

• cellucid/markdown/DOCUMENTATION_SCREENSHOTS_AND_FIGURES_GUIDE.md

Recommended screenshot set (core interactions)

Navigation modes (3 screenshots)

1. Orbit mode (with orbit anchor visible)

2. Planar mode (with zoom-to-cursor toggle visible)

3. Free-fly mode (with Capture pointer visible)

You can capture these from:

• c_core_interactions/01_navigation_modes_orbit_planar_free_fly

Multiview badges + indicators (1–2 screenshots)

Capture:

• at least 2 snapshots,

• grid compare layout,

• cameras unlocked (so Orb/Pan/Fly badges show),

• a visible dimension badge (e.g. 3D).

Page:

• c_core_interactions/04_view_layout_live_snapshots_small_multiples

Dimension switching (2 screenshots)

1. Dimension dropdown open showing available dims

2. Before/after switching dimensions (same view)

Page:

• c_core_interactions/05_dimension_switching_1d_2d_3d

Render modes (2 screenshots)

1. Points mode (with render mode dropdown visible)

2. Smoke mode (with smoke controls visible)

Page:

• c_core_interactions/03_render_modes_points_vs_volumetric_smoke

Highly recommended “failure mode” screenshots (debugging gold)

These save huge amounts of time in support and onboarding:

• WebGL context lost overlay (requires reload)

• Smoke mode blank/slow (with grid + ray quality visible)

• Pointer lock active (cursor hidden) and how to exit (Esc)

System requirements page includes a placeholder for the context-lost overlay:
