Radiance Plastic2 Material.
Plastic2 is similar to plastic, but with anisotropic roughness. This means that highlights in the surface will appear elliptical rather than round. The orientation of the anisotropy is determined by the unnormalized direction vector ux uy uz. These three expressions (separated by white space) are evaluated in the context of the function file funcfile. If no function file is required (i.e., no special variables or functions are required), a period (‘.’) may be given in its place. (See the discussion of Function Files in the Auxiliary Files section). The urough value defines the roughness along the u vector given projected onto the surface. The vrough value defines the roughness perpendicular to this vector. Note that the highlight will be narrower in the direction of the smaller roughness value. Roughness values of zero are not allowed for efficiency reasons since the behavior would be the same as regular plastic in that case.

- 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: []).

- 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.

- 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], [], [] ]
