-
lenght
float d = length(P);
distance
float d = distance(P, {1,0,3} );
d = ch('scale');
Cd = (sin(d)+1)0.5;
clamp
float d = length(P);
P.y = clamp(d,0,3);
fit
float d = length(P);
P.y = fit(d,1,2, 1, 2);
-
minpos
vector pos = minpos(1,P);
float d = distance(P, pos);
d *= ch('scale');
Cd = 0;
Cd.r = sin(d);
-
nearpoint
int pt = nearpoint(1,P);
Cd = point(1,'Cd',pt);
