Detailed Description

template<typename PType = double*>
struct QTreeNB< PType >

QTreeNB: Tree structure used for force calculation with particles (i.e. stars, Nbody or halos).

The tree also contains pointers to the list of positions, sizes and masses of the particles. Also flags for the number of dimensions the tree is defined in (2 or 3), and if multiple masses and sizes should be used.

The documentation for this struct was generated from the following file:

SLsimLib/include/qTreeNB.h
