How it works

When you open several windows (for example, comparing different configurations or ensembles), the visualiser keeps their cameras in sync:

make open FILES="surface_data/config_a.surf surface_data/config_b.surf"

• The window with focus writes its full viewing state (rotation matrices, angles, zoom, focus radius, selection centre, slice position, mode) to /tmp/vortex_shared.bin every frame.
• Every unfocused window reads that file at 10 Hz and mirrors the state, then sleeps.

Click any window to make it the leader; the others follow. This makes it easy to inspect the same region of spacetime across different configurations with identical camera parameters.

Details

• Time-axis values are shared as fractions of Nt, so windows on lattices with different temporal extents stay aligned.
• The leader also propagates mode changes and timeslice position.
• The state file lives in /tmp and is recreated on every launch; stale files are harmless.
