Signature: (x(); y(); z(); float [o]coords(tri=3);)
Combine three coordinates into a single piddle.
Combine x, y and z to a single piddle the first dimension of which is 3. This routine does dataflow automatically.
Signature: (coords(nc,np); [o]vecs(nc,np); int [t]links(np);; double boxsize; int dmult; double a; double b; double c; double d; )
Repulsive potential for molecule-like constructs.
repulse
uses a hash table of cubes to quickly calculate a repulsive force that
vanishes at infinity for many objects. For use by the module
PDL::Graphics::TriD::MathGraph. For definition of the potential, see the
actual function.
Signature: (coords(nc,np); int from(nl); int to(nl); strength(nl); [o]vecs(nc,np);; double m; double ms; )
Attractive potential for molecule-like constructs.
attract
is used to calculate an attractive force for many objects, of which some
attract each other (in a way like molecular bonds). For use by the module
PDL::Graphics::TriD::MathGraph. For definition of the potential, see the
actual function.
Signature: (vertices(n=3); char* space; char* fd)
