Bases:
Measure
Radiance meter array measure scene element [
mradiancemeter
,multi_radiancemeter
].This measure scene element is a thin wrapper around the
mradiancemeter
sensor kernel plugin. It records the incident power per unit area per unit solid angle along a number of rays defined by itsorigins
anddirections
parameters.- Parameters:
id (
str
, optional, default:"measure"
) – Identifier of the current scene element.spectral_cfg (
MeasureSpectralConfig
ordict
, default:MeasureSpectralConfig.new()
) – Spectral configuration of the measure. Must match the current operational mode. Can be passed as a dictionary, which will be interpreted byMeasureSpectralConfig.from_dict()
.sampler (
{"independent", "stratified", "multijitter", "orthogonal", "ldsampler"}
, default:"independent"
) – Mitsuba sampler used to generate pseudo-random number sequences.spp (
int
, default:1000
) – Number of samples per pixel.origins (array-like, default:
[[0
,0
,0]] m
) – A sequence of points specifying radiance meter array positions.Unit-enabled field (default: ucc[‘length’]).
directions (array-like, default:
[[0
,0
,1]]
) – A sequence of 3-vectors specifying radiance meter array directions.
- Fields:
spectral_cfg (
MeasureSpectralConfig
) – Spectral configuration of the measure.sampler (
str
) – Mitsuba sampler used to generate pseudo-random number sequences.spp (
int
) – Number of samples per pixel.origins (
quantity
) – A sequence of points specifying radiance meter array positions.directions (
quantity
) – A sequence of 3-vectors specifying radiance meter array directions.
- is_distant()#
Return
True
iff measure records radiometric quantities at infinite distance.
- traverse(callback)#
Traverse this scene element and collect kernel dictionary template and parameter update map contributions.
- Parameters:
callback (
SceneTraversal
) – Callback data structure storing the collected data.
- update()#
Enforce internal state consistency. This method should be called when fields are modified. It is automatically called as a post-init step.
- property objects#
Map of child objects associated with this scene element.
- Returns:
dict
– A dictionary mapping object names to a corresponding object to be inserted in the Eradiate scene graph.
- property params#
- Returns:
dict[str
,UpdateParameter
] orNone
– A dictionary mapping parameter paths, consisting of dot-separated strings, to a corresponding update protocol.

- property template#
Kernel dictionary template contents associated with this scene element.
- Returns:
dict
– A flat dictionary mapping dot-separated strings describing the path of an item in the nested scene dictionary to values. Values may be objects which can be directly used by themitsuba.load_dict()
function, orInitParameter
instances which must be rendered.
