Core Interactions (Viewer Basics)#
These pages explain how to drive the viewer confidently: navigation, camera, render modes, multiview, and switching embeddings.
Audience: everyone (novices get click-by-click; power users get exact controls + edge cases)
Time: 15–30 minutes for full coverage
Recommended reading order
Camera controls (advanced) (when you want to tune)
Troubleshooting (core interactions) (when something feels “stuck”)
Verified core-interaction captures (every control on this page, photographed)
Where these controls live#
Everything in this section is in three sidebar accordions: Visualization, Navigation and Compare views. Navigation is the one you will use most; it edits the selected view, and it changes shape with the mode you pick:
The Navigation block in Orbit mode, the default for a 3D embedding. The
Mode dropdown is the control this whole section revolves around.#
Orbit vs planar vs free‑fly, with exact mouse/keyboard mappings and focus rules.
Look sensitivity, movement speed, pointer lock, orbit anchor, and reset behavior.
Points vs volumetric smoke, including performance knobs and failure modes.
Keep view, grid compare, the view rows, linked cameras, and per‑view state.
Which embedding each view shows, keys 1/2/3, what changes, and what doesn’t.
Symptom → diagnosis → fix for “can’t rotate”, “controls disappear”, “smoke blank”, “context lost”, and more.
The navigation, render-mode, dimension, multiview and camera-path controls as they appear in the running app.
