- Persistent `Layout3dSolver` for realtime frame-by-frame iteration.
- Warm-start positions for graph edits and interaction.
- Spatial-grid approximate repulsion for the 3D solver.
- Barnes-Hut octree repulsion for the 3D solver.
- Spatial-grid approximate repulsion as a simpler fallback.
- SCC detection for cyclic bodies.
- weak components for broad spatial islands.
- articulation points and bridges for hinge-like connectors.
@ -72,13 +73,14 @@ crate is adaptive step control and Barnes-Hut for large interactive layouts.
Implementation direction:
- Replace fixed cooling with adaptive speed.
- Upgrade spatial-grid repulsion to Barnes-Hut for far-field approximation.
- Tune Barnes-Hut and add benchmarks against exact/grid modes.
- Expose live-tick APIs for Bevy interaction instead of only batch layout.
Current state:
- `Layout3dSolver` exists.
- `RepulsionMode::SpatialGrid` is the default realtime path.
- `RepulsionMode::BarnesHut` is the default realtime path.
- `RepulsionMode::SpatialGrid` remains available as a simpler local approximation.
- `RepulsionMode::Exact` remains available for small graphs and comparisons.
