Detailed Description

Linear combination of different BSDF implementations, where the coefficients are determined either a priori (inherent property described in scenefile) or via a texture map lookup.

Note:

aggregate corresponds to the underlying Milton class 'AggregateBSDF.'

Attribute Documentation

array [bsdf] aggregate::bsdfs

Array of sub-bsdfs of length n which this aggregate bsdf is composed of.

type	array[bsdf]
optional	false
restrictions	must be non-empty and have the same length as weights

array [clampedSpectrum] aggregate::weights

Array of weighting coefficients for sub-bsdfs of length n, specifying what fraction of each sub-bsdf this aggregate bsdf is composed of.

Note:

Array of weights does not need to be normalized, and since individual weights are clampedSpectrum elements themselves, they may be mapped over the surface of the material (eg, via a "weight" texture map)

type	array[clampedSpectrum]
optional	false
restrictions	must be non-empty
