The Grouping
Modeled · numerical
How does a group of nearby paths spread?
Fire the same bundle with Dispersion off and on. Compare its shape and spread after each reset.

About this tool
What you are looking at
A group of nearby starting points moves through the same simulated billiard. In the displayed run, the circular scatterer stretches and folds the bundle; without it, the group remains a translated segment. Filament length and spread are finite-run display measures, not Lyapunov exponents, entropy measurements, or proof of behavior for every orbit.
How to use it
Set the number of shots and muzzle spread, toggle Dispersion, then select Fire. Read filament length and group spread relative to their initial values, along with the tightest-regroup note. Compare scatterer-on and scatterer-off runs from the reset state.
