Region styles
=============
Classes that define geometric regions are derived from the Region
class. Regions are used elsewhere in LAMMPS to group atoms, delete
atoms to create a void, insert atoms in a specified region, etc. New
styles can be created to add new region shapes to LAMMPS.
Region\_sphere.cpp is an example of a spherical region.
Here is a brief description of methods you define in your new derived
class. See region.h for details.
+-------------------+---------------------------------------------------------------------+
| inside | determine whether a point is in the region |
+-------------------+---------------------------------------------------------------------+
| surface\_interior | determine if a point is within a cutoff distance inside of surface |
+-------------------+---------------------------------------------------------------------+
| surface\_exterior | determine if a point is within a cutoff distance outside of surface |
+-------------------+---------------------------------------------------------------------+
| shape\_update | change region shape if set by time-dependent variable |
+-------------------+---------------------------------------------------------------------+
