Bases: eradiate.scenes.measure._core.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 its origins and directions parameters.

Parameters

  • id (str, optional, default: "measure") – User-defined object identifier.

  • spectral_cfg (MeasureSpectralConfig or dict, default: MeasureSpectralConfig.new()) – Spectral configuration of the measure. Must match the current operational mode. Can be passed as a dictionary, which will be interpreted by MeasureSpectralConfig.from_dict().

  • spp (int, default: 1000) – Number of samples per pixel.

  • split_spp (int, optional) – If set, this measure will be split into multiple sensors, each with a sample count lower or equal to split_spp. This parameter should be used in single-precision modes when the sample count is higher than 100,000 (very high sample count might result in floating point number precision issues otherwise).

  • 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

  • id (str or None) – User-defined object identifier.

  • spectral_cfg (MeasureSpectralConfig) – Spectral configuration of the measure.

  • spp (int) – Number of samples per pixel.

  • split_spp (int) – If set, this measure will be split into multiple sensors, each with a sample count lower or equal to split_spp.

  • 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.

is_split()#

Return True iff sample count split shall be activated.

kernel_dict(ctx)[source]#

Return a dictionary suitable for kernel scene configuration.

Parameters

ctx (KernelDictContext) – A context data structure containing parameters relevant for kernel dictionary generation.

Returns

KernelDict – Kernel dictionary which can be loaded as a Mitsuba object.
