Finally implemented perceptual brightness thing.

function z=vlinterp_d(k,z0,d)
% vlinterp_d - linear interpolation between two points
%
% vlinterp_d :: 
%    real   ~'fraction of distance to travel from from initial to final point',
%    [Size] ~'initial point',
%    [Size] ~'vector from initial to final point'
% -> [Size] ~'interpolated point'.
%
% Definition is vlinterp_d(k,z0,d) = vlinterp(k,z0,z0+d)

z = z0+k*d;
