Known Subclasses:

Class to draw a 3D tetrahedron in Maestro's Workspace.

See doc string for __init__ for details on instantiation.

Tetrahedrons should be added to a graphics3d.common.Group, 
or TetrahedronGroup, and drawing done via the Group.  
See the L{graphics3d.common.Group} documentation.


API Example
-----------
import schrodinger.maestro.maestro as maestro
import schrodinger.graphics3d.polyhedron as polyhedron

tetrahedron_grp = polyhedron.Group()
st = maestro.workspace_get() # Here, st is methane.
for atom in st.atom:
    if atom.element == 'C':
        center = atoms.xyz

tetra = polyhedron.Tetrahedron(
    center  = center,
    length  = 1.828, # length between Hs
    color   = 'goldenrod',
    opacity = 1.0,
    style   = tetrahedron.LINE
)
# Add the primative to the container.
tetrahedron_grp.add(tetra)

# Add the draw callback.
maestro.workspace_draw_function_add(tetrahedron_grp.draw)

# Hide the markers.
tetrahedron_grp.hide()

# Remove the markers and the callback.
tetrahedron_grp.clear()

__init__(self, center, mode, length=None, radius=None, volume=None, color='red', opacity=1.0, style=1)
(Constructor)

 

Create a polyhedron centered at center. Note that one of length, radius, volume is needed to create the shape.

Parameters:
  • center - List of 3 Angstrom values indicating the center coordinate of the tetrahedron.
  • length - Length in Angstroms of each of the edges of the tetrahedron.
  • radius - Circumsphere radius in Angstroms from center of tetrahedron.
  • volume - Volume in cubed Angstroms of the object.
  • color - One of - Color object, Color name (string), or Tuple of (R, G, B) (each 0.0-1.0)
  • opacity - 0.0 (invisible) through 1.0 (opaque). Defaults to 1.0
  • style - LINE or FILL. Default is FILL.
Raises:
  • RuntimeError - If a single option from length, radius, and volume does not have a value.
  • ValueError - If the size parameter (length, radius, or volume) is not a float.
  • NotImplementedError - If the initiating subclass does not have a getVertices or getFaces method.
Overrides: object.__init__

See Also: MaestroPolyhedronCore.__init__

getVertices(self, center, length=None, radius=None, volume=None)

 

Get a list of vertices. If the center coordinates are considered the origin the vertices will have a base on the y-plane, a vertex on the x-axis and a vertex directly in the +z-axis from the center.

Parameters:
  • center (List) - List of 3 Angstrom values indicating the center coordinate of the tetrahedron.
  • length (float) - Length in Angstroms of each of the sides of the tetrahedron. Note: length or radius must be specified to create tetrahedron.
  • radius (float) - Circumsphere radius in Angstroms from center of tetrahedron. Note: length or radius must be specified to create tetrahedron.
  • volume (float) - Volume in cubed Angstroms of the object.
Overrides: MaestroPolyhedronCore.getVertices

getIndices(self)

 

@return The indices of the faces

Overrides: MaestroPolyhedronCore.getIndices
