Chemistry::3DBuilder - Generate 3D coordinates from a connection table

    # example: convert SMILES to MDL molfile
    use Chemistry::3DBuilder qw(build_3d);
    use Chemistry::File::SMILES;
    use Chemistry::File::MDLMol;

    my $s = '[O-]C(=O)C(N)C(C)CC';
    my $mol = Chemistry::Mol->parse($s, format => 'smiles');

    build_3d($mol);

    print $mol->print(format => 'mdl');

This module generates a three-dimensional molecular structure from a connection table, such as that obtained by a 2D representation of the molecule or from a SMILES string.

NOTE: this module is still at a very early stage of development so it has important limitations. 1) It doesn't handle rings or stereochemistry yet! 2) The bond lengths and atoms are very approximate as they don't really account for different elements. 3) Only the sp3, sp2, and sp hybridizations are supported.

These subroutines may be exported; to export all, use the ':all' tag.

build_3d($mol)

Add internal and cartesian coordinates to the molecule $mol.
