- class honeybee_radiance.modifier.material.metfunc.Metfunc(identifier, modifier=None, values=None, is_opaque=None, dependencies=None)[source]¶
Bases:
Material
Radiance Metfunc Material.
Metfunc is identical to plasfunc and takes the same arguments, but the specular component is multiplied also by the material color.
- Parameters
identifier – Text string for a unique Material ID. Must not contain spaces or special characters. This will be used to identify the object across a model and in the exported Radiance files.
modifier – Modifier. It can be primitive, mixture, texture or pattern. (Default: None).
values – An array 3 arrays for primitive data. Each of the 3 sub-arrays refer to a line number in the radiance primitive definitions and the values in each array correspond to values occurring within each line.
is_opaque – A boolean to indicate whether this primitive is opaque.
dependencies – A list of primitives that this primitive depends on. This argument is only useful for defining advanced primitives that are defined based on other primitives. (Default: []).
- Properties:
identifier
display_name
values
modifier
dependencies
is_modifier
is_material
is_opaque
- ToString()¶
Overwrite .NET ToString.
- add_dependent(dep)¶
Add dependent.
- duplicate()¶
Get a copy of this object.
- static filter_dict_input(input_dict)¶
Filter a dictionary of a Primitive to get modifier and dependency objects.
- classmethod from_dict(data)¶
Initialize the object from a dictionary.
- Parameters
data – A dictionary in the format below.
{ "modifier": {}, # primitive modifier (Default: None) "type": "", # lowercase string for the primitive type "identifier": "", # primitive identifier "display_name": "", # primitive display name "values": [], # values "dependencies": [] }
- classmethod from_primitive_dict(primitive_dict)¶
Initialize the object from a primitive dict.
The primitive_dict is a dictionary following the base Primitive schema of a Radiance object. This base Primitive schema is the same for all Radiance Primitives (including Modifiers and Geometry) whereas the from_dict classmethod accepts a different schema that is customized to each subclass inheriting from the Radiance Primitive.
- Parameters
data – A dictionary in the format below
{ "modifier": {}, # primitive modifier (Default: None) "type": "", # lowercase string for the primitive type "identifier": "", # primitive identifier "display_name": "", # primitive display name "values": [], # values "dependencies": [] }
- classmethod from_string(primitive_string)¶
Create a Radiance primitive from a string.
If the primitive modifier is not void or it has other dependencies, the modifier and/or dependencies must also be part of the input string.
- lock()¶
- to_dict()¶
Translate this object to a dictionary.
- to_radiance(minimal=False, include_modifier=True, include_dependencies=True)¶
Return full radiance definition.
- Parameters
minimal – Boolean to note whether the radiance string should be written in a minimal format (with spaces instead of line breaks). Default: False.
include_modifier – Boolean to note whether the modifier of this primitive should be included in the string. Default: True.
include_dependencies – Boolean to note whether the dependencies of this primitive should be included in the string. Default: True.
- unlock()¶

- property dependencies¶
Get list of dependencies for this primitive.
Additional dependencies can be added with the add_dependent method.
- property display_name¶
Get or set a string for the object name without any character restrictions.
If not set, this will be equal to the identifier.
- property identifier¶
Get or set a text string for the unique primitive identifier.
- property is_geometry¶
Get a boolean noting whether this object is a Radiance geometry.
- property is_material¶
Get a boolean noting whether this object is a material modifier.
- property is_mixture¶
Get a boolean noting whether this object is a mixture modifier.
- property is_modifier¶
Get a boolean indicating whether this object is a Radiance modifier.
Modifiers include materials, mixtures, textures and patterns.
- property is_opaque¶
Get or set a boolean to indicate whether this primitive is opaque.
This property is used to separate opaque and non-opaque geometries as well as modifiers.
- property is_pattern¶
Get a boolean noting whether this object is a pattern modifier.
- property is_texture¶
Get a boolean noting whether this object is a texture modifier.
- property is_void¶
Only true for a void.
- property modifier¶
Get or set an object for the primitive modifier.
- property type¶
Get or set a string for the primitive type.
This should always be lower case in order to match the radiance convention.
- property values¶
Get or set the values of the current primitive as a list of three lists.
Each sub-list represents a line of the primitive’s radiance representation and contain the properties that define the primitive.
Usage:
# This will erase all values except the first line, which has 9 custom items primitive.values = [ [0.5, 0.5, 0.5, "/usr/oak.pic", ".", "frac(U)", "frac(V)", "-s", 1.1667], [], [] ]
