Parameters:

  • identifier – Text string for a unique Geometry 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.

  • center_pt – Sphere center point as (x, y, z) (Default: (0, 0 ,0)).

  • radius – Sphere radius as a number (Default: 10).

  • modifier – Geometry modifier (Default: None).

  • dependencies – A list of primitives that this primitive depends on. This argument is only useful for defining advanced primitives where the primitive is defined based on other primitives. (Default: [])

Properties:

  • identifier

  • display_name

  • center_pt

  • radius

  • modifier

  • dependencies

  • values

Usage:

sphere = Sphere("test_sphere", (0, 0, 10), 10)
print(sphere)
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)[source]

Initialize a Sphere from a dictionary.

Parameters:

data – A dictionary in the format below.

{
"type": "sphere",  # Geometry type
"modifier": {} ,
"identifier": "",  # Geometry identifier
"display_name": "",  # Geometry display name
"center_pt": {"x": float, "y": float, "z": float},
"radius": float,
"dependencies": []
}
classmethod from_primitive_dict(primitive_dict)[source]

Initialize a Sphere from a primitive dict.

Parameters:

data – A dictionary in the format below.

{
"modifier": {},  # primitive modifier (Default: None)
"type": "sphere",  # 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()[source]

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 center_pt

Sphere center point as (x, y, z). Default is (0, 0 ,0).

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 radius

Sphere radius as a number. Default is 10.

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],
    [],
    []
