The class vtkGlyphModule implements the lower-level objects for representing predefined shapes (glyphs) in
VTK.
class ase.visualize.vtk.module.vtkGlyphModule(vtk_pointset, glyph_source, scalemode=None,
colormode=None)
Modules represent a unified collection of VTK objects needed for introducing basic visualization concepts
such as surfaces or shapes.
A common trait of all modules is the need for an actor representation and corresponding generic properties
such as lighting, color and transparency.
Poly data modules are based on polygonal data sets, which can be mapped into graphics primitives suitable
for rendering within the VTK framework.
Glyph modules construct these polygonal data sets by replicating a glyph source across a specific set of
points, using available scalar or vector point data to scale and orientate the glyph source if desired.
Example:
>>> atoms = molecule(’C60’)
>>> cell = vtkUnitCellModule(atoms)
>>> apos = vtkAtomicPositions(atoms.get_positions(), cell)
>>> vtk_ugd = apos.get_unstructured_grid()
>>> glyph_source = vtkAtomSource(’C’)
>>> glyph_module = vtkGlyphModule(vtk_ugd, glyph_source)
Construct VTK-representation of a module containing glyphs. These glyphs share a common source, defining
their geometrical shape, which is cloned and oriented according to the input data.
vtk_pointset: Instance of vtkPointSet or subclass thereof A vtkPointSet defines a set of positions,
which may then be assigned specific scalar of vector data across the entire set.
glyph_source: Instance of ~vtk.vtkCustomGlyphSource or subclass thereof Provides the basic shape
to distribute over the point set.
get_actor()
Return the actor representing this module in a rendering scene.
set_actor(vtk_act)
Set the actor representing this module in a rendering scene.
set_property(vtk_property)
Set the property of the actor representing this module.
