Figure 8. Marker atoms in a deforming crystal
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 modifier's Create selection option to let the modifier select the atoms instead of deleting them.
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.
