schrodinger.graphics3d.polygon module¶
OpenGL polygons.
The polygon module allows creation and drawing of polygons. Clients draw using Group instances not through Polygon instances.
Drawing is done in whatever is the current GL rendering context and current GL window. So you must set those prior to drawing. If you are using this with Maestro’s drawing callback mechanism you need not worry about the above details. These are handled for you automatically.
Control over the vertices, color, and transparency of a polygon are provided. See the Polygon class for more info.
To draw any number of polygons create the Polygon instances and add them to a Group instance (PolygonGroup can be used and is a synonym). Then invoke the Group’s draw() method.

class
schrodinger.graphics3d.polygon.
Polygon
(vertices, color=None, opacity=1.0, style=1)¶ Bases:
schrodinger.graphics3d.common.Primitive
Class to draw a flat polygon in OpenGL. Will be drawn in the current OpenGL drawable. This includes the ability to draw into Maestro’s Workspace. It just needs to be the current drawable.
API Example:
import schrodinger.maestro.maestro as maestro import schrodinger.graphics3d.common as common import schrodinger.graphics3d.polygon as polygon import math poly_grp = common.Group() st = maestro.workspace_get() at = st.atom[1] vertices = [] for theta in range(0, 360, 80): theta_rad = theta * math.pi/180 x = math.cos(theta_rad) y = math.sin(theta_rad) vertices.append( (at.x + x, at.y + y, at.z) ) pgon = polygon.Polygon( vertices=vertices, color='red', opacity=0.8, ) # Add the primative to the container. poly_grp.add(pgon) # Hide the markers. poly_grp.hide() # Remove the markers and the callback. poly_grp.clear() maestro.workspace_draw_function_remove(poly_grp.draw)
-
__init__
(vertices, color=None, opacity=1.0, style=1)¶ Constructor requires:
- vertices: List of vertex coordinates (x, y, z).
- Specify at least 3 vertices in consecutive order. All vertices must be in the same plane.
- color: One of:
- Color object (Color class) Color name (string) Tuple of (R, G, B) (each a float in range 0.0-1.0)
Optional arguments:
- opacity: 0.0 (invisible) through 1.0 (opaque)
- Defaults to 1.0
style: LINE or FILL. Default is FILL.

__init_subclass__
()¶ This method is called when a class is subclassed.
The default implementation does nothing. It may be overridden to extend subclasses.

__subclasshook__
()¶ Abstract classes can override this to customize issubclass().
This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).
