Limitations

The particle spacings may be not exactly as specified in order to create a smooth surface.

Resultant geometries of boolean operations can have more particles than expected in some cases, because

• For intersection and subtraction, only particles with distances smaller than rmax will be identified the same. Users should align particles of different geometries to get the expected results.

• For union, particles of all the given geometries will be collected to yield the union. Users should ensure no particles are overlapped.

rmax can also be increased appropriately so that more particles can be identified the same.
