Calculates coordinates and colorimetric variables that represent reflectance spectra in the color opponent coding model of hymenopteran vision.
Arguments
- vismodeldata
(required) quantum catch colour data. Can be either the result from
vismodel()
or independently calculated data (in the form of a data frame with three columns named 's', 'm', 'l', representing a trichromatic viewer).
Value
A data frame of class colspace
consisting of the following columns:
s
,m
,l
: the quantum catch data used to calculate the remaining variables.x
,y
: coordinates for the points in coc spacer.vec
: the r vector (saturation, distance from the center using a city-block metric).
