Map (Legacy)
Map (Legacy) is the original Three.js map scene. Mantis now defaults to a faster WebGL renderer, but a number of features were never ported to it, so the legacy scene is still shipped and is the only place those features run. Open it when something you need is missing from Map.
Where to find it
View > Exploration > Map (Legacy). It opens as its own tab and shares the space’s points, clusters, selection and bags with the default map, so anything you select in one is visible to panels driven by the other.
What only works here
| Feature | What you get |
|---|---|
| Hand-gesture control | Toggle with Ctrl+⇧+H or the hand icon in the right-hand toolbox. Camera, cursor, gaze and calibration overlays all render into this scene. |
| Right-click selection menu | With points selected, right-click the canvas for a menu of panels that can act on the selection, grouped into Inspect, Analyze, Visualize, Summarize and Export. |
| In-scene journey paths | A journey’s stops are turned into a smooth camera path and flown, rather than jumped to. |
| In-scene gradients | Gradient color planes, animated field lines with arrowheads, hotspot outlines and the 3D gradient surface are all rendered inside this scene. The gradient views embed this map for exactly that reason. |
| Geographic backdrops | Views whose backdrop is set to Geo Tiles draw map tiles under the points. |
| Semantic Ruler | Pick two points and read their true high-dimensional cosine similarity, not their on-screen distance. Shortcut R. |
| Journey tool | Draw a path through the map, then click Create Journey from Path to save the traversal as a journey. Shortcut J. |
| Waypoint tool | Save the current camera and selection state as a named waypoint. |
| On-map search | The search box over the canvas matches points by title and labels the matches in the scene. |
| Spider lines | Press S to draw arcs from the selection’s center to each selected point. Arc height, thickness and opacity are adjustable. |
| Flashcards on the map | Render selected points as cards laid out around the map, with count, box size, arm length and spread angle controls. |
| Drawing on views | Views with a canvas overlay let you draw directly over the backdrop. |
Trajectories, link arcs, projection pins, citation markers from the Composer, mindmap overlays and the localized-error overlay also render in this scene.
The tool palette
The legacy toolbar carries the full twelve-entry palette, not the seven interaction modes of the default map:
Select (I), Lasso (Q), Magic Lasso (M), Path (P), Landmark (N), Waypoint, Clear Bags, Delete Bags, Journey (J), Reconstruct, Semantic Ruler (R) and Heatmap (H).
Two of those are actions, not modes, and their names understate what they do:
Important
Clear Bags does not empty a bag. It clears the current selection, on every open map. Shortcut Ctrl+⌫.
Delete Bags deletes every bag on every open map, with no confirmation and no undo. Shortcut Ctrl+⇧+⌫.
The right-hand toolbox
A narrow vertical toolbox sits at the bottom right of the scene:
- Rearrange bags, shown once you have three or more bags, to declutter their bubbles.
- Recenter map to selected points.
- Flashcards settings, with a link to the full Flashcards panel.
- Spider mode and its arc controls.
- 2.5D and 2D view mode. There is no 3D button; the toggle for it is commented out in the source.
- Gesture mode.
- Toggle map controls, which hides or shows the on-map widgets. The keyboard equivalent is Ctrl+M.
The bottom left carries the point-coloring legend and the band-pass range filter. Two minimaps sit at the top: a text minimap on the left and a camera minimap on the right.
Limits
- It is the slower renderer. On large spaces, prefer the default Map for everyday panning, zooming and selection, and switch here for the features above.
- Boundary modes, the draggable tool island and the draggable control widgets are specific to the default map and do not exist here.
