Marker atoms can be used to make the internal deformation in a solid visible as shown
in the example on the right. Another possible application is tracking diffusing
particles in a fluid over the course of a simulation.
The example animation has been created as follows:
First we apply the Slice modifier at frame 0 of the simulation (the initial state) to select a stripe of atoms. Activate the Select particles option to let the modifier create a selection (instead of deleting atoms).
We then apply the Freeze property
modifier and choose the Selection
particle property as the one
to be frozen. The modifier automatically takes a snapshot of the particle selection state
generated by the Slice modifier and preserves it over time.
Finally the Assign color modifier is used to assign a special marker color to the selected particles.
