Detailed Description

class describing a molecule

vtkMolecule and the convenience classes vtkAtom and vtkBond describe the geometry and connectivity of a molecule. The molecule can be constructed using the AppendAtom() and AppendBond() methods in one of two ways; either by fully specifying the atom/bond in a single call, or by incrementally setting the various attributes using the convenience vtkAtom and vtkBond classes:

Single call:

vtkMolecule *mol = vtkMolecule::New();
vtkAtom h1 = mol->AppendAtom(1, 0.0, 0.0, -0.5);
vtkAtom h2 = mol->AppendAtom(1, 0.0, 0.0,  0.5);
vtkBond b  = mol->AppendBond(h1, h2, 1);

Incremental:

vtkMolecule *mol = vtkMolecule::New();
 
vtkAtom h1 = mol->AppendAtom();
h1.SetAtomicNumber(1);
h1.SetPosition(0.0, 0.0, -0.5);
 
vtkAtom h2 = mol->AppendAtom();
h2.SetAtomicNumber(1);
vtkVector3d displacement (0.0, 0.0, 1.0);
h2.SetPosition(h1.GetPositionAsVector3d() + displacement);
 
vtkBond b  = mol->AppendBond(h1, h2, 1);

Both of the above methods will produce the same molecule, two hydrogens connected with a 1.0 Angstrom single bond, aligned to the z-axis. The second example also demonstrates the use of VTK's vtkVector class, which is fully supported by the Chemistry kit.

The vtkMolecule object is intended to be used with the vtkMoleculeMapper class for visualizing molecular structure using common rendering techniques.

Warning: While direct use of the underlying vtkUndirectedGraph structure is possible due to vtkMolecule's public inheritance, this should not be relied upon and may change in the future.

If the plane is set successfully, the function returns true.

If the normal is not orthogonal to the bond, a new normal will be constructed in such a way that the plane will be orthogonal to the plane spanned by the bond vector and the input normal vector.

This ensures that the plane passes through the bond, and the normal is more of a "hint" indicating the orientation of the plane.

The new normal (n) is defined as the input normal vector (n_i) minus the projection of itself (proj[n_i]_v) onto the bond vector (v):

* v ^
* |  n = (n_i - proj[n_j]_v)
* proj[n_i]_v ^  |----x
* |  |   /
* |  |  / n_i
* |  | /
