Detailed Description

3D integer bounding box for grid index space

Defines the Box3D class which represents a discrete 3D rectangular region in grid index space. This is used to describe local computational domains in parallel simulations.

Box3D operates purely in index space and is independent of physical coordinates, spacing, or origin. It is typically paired with World for coordinate transformations.

#include <openpfc/core/box3d.hpp>
 
// Create a box from (0,0,0) to (63,63,63)
pfc::Box3D box({0, 0, 0}, {64, 64, 64});
auto size = box.size();  // Returns {64, 64, 64}
