NAME

PDL::Graphics::TriD::Rout - Helper routines for Three-dimensional graphics

DESCRIPTION

This module is for miscellaneous PP-defined utility routines for the PDL::Graphics::TriD module. Currently, there are #line 39 "Rout.pm"

FUNCTIONS

combcoords

  Signature: (x(); y(); z();
		float [o]coords(tri=3);)

Combine three coordinates into a single ndarray.

Combine x, y and z to a single ndarray the first dimension of which is 3. This routine does dataflow automatically.

combcoords does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

repulse

  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.

repulse does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

attract

  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.

attract does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

vrmlcoordsvert

Signature: (vertices(n=3); char* space; PerlIO *fp)

info not available

vrmlcoordsvert does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.
