dispace: Dichromatic colour space

Description

Calculates coordinates and colorimetric variables that represent reflectance spectra in a dichromatic colour space.

Usage

dispace(vismodeldata)

Arguments

vismodeldata

(required) quantum catch color data. Can be either the result from vismodel or independently calculated data (in the form of a data frame with two columns representing dichromatic viewer).

Value

A data frame of class colspace consisting of the following columns:

s, l: the quantum catch data used to calculate the remaining variables.

x: the coordinate of the stimulus along a segment

r.vec: the r vector (saturation, distance from the center).
