Return to the laboratory and drag the gas sample tube off the stockroom counter and place it in the middle of the table as indicated by the spotlight. WitrynaIn a spectral renderer, we treat each wavelength independently. We transform to tristimulus values only at the end of the evaluation. Each reflectance and illuminant have then to be specified as a spectrum. In a tristimulus renderer, we treat each reflectance and illuminant as tristimulus values and multiply them.
