add_shading_to_face(face, tolerance=0.01)[source]

Add Shades to a Honeybee Face using these Shading Parameters.

Parameters:

  • face – A honeybee-core Face object.

duplicate()

Get a copy of this object.

classmethod from_dict(data)[source]

Create ExtrudedBorder from a dictionary.

{
"type": "ExtrudedBorder",
"depth": 0.5
}
scale(factor)[source]

This method is called within the scale methods of the Room2D.

Parameters:

factor – A number representing how much the object should be scaled.

class dragonfly.shadingparameter.LouversByCount(louver_count, depth, offset=0, angle=0, contour_vector=Vector2D(0.00, 1.00), flip_start_side=False)[source]

Bases: _LouversBase

Instructions for a specific number of louvered Shades over a wall.

Parameters:

  • louver_count – A positive integer for the number of louvers to generate.

  • depth – A number for the depth to extrude the louvers.

  • offset – A number for the distance to louvers from the wall. Default is 0 for no offset.

  • angle – A number for the for an angle to rotate the louvers in degrees. Default is 0 for no rotation.

  • contour_vector – A Vector2D for the direction along which contours are generated. This 2D vector will be interpreted into a 3D vector within the plane of the wall. (0, 1) will usually generate horizontal contours in 3D space, (1, 0) will generate vertical contours, and (1, 1) will generate diagonal contours. Default: (0, 1).

  • flip_start_side – Boolean to note whether the side the louvers start from should be flipped. Default is False to have contours on top or right. Setting to True will start contours on the bottom or left.

Properties:

  • louver_count

  • depth

  • offset

  • angle

  • contour_vector
