Changing layout theta
The layout theta determines the accuracy of the Barnes–Hut approximation computation;
larger values increase the speed of the simulation but lower its accuracy. When theta is
0
, the algorithm becomes a direct-sum algorithm.
To change the layout theta setting, navigate to the Marks menu, and
change value for Layout theta option. The default setting is
0.8
.
