point position in Y to Cd

[DiegoAP]

hi, everyone, I'm trying to make a function that gets the minimum value in P.y and colors the dot in case it's the minimum.

You can use a point wrangle for that and type code. This will make points lower than 0.1 on 1 the color red.

if(v@P.y<0.1){v@Cd = set(1,0,0);}

You can also run a point wrangle to set a detail attribute for the minimum value:

setdetailattrib(0, "minY", @P.y, "min");

Then followed by another point wrangle to read that & assign red to the point that matches that value in Y:

float min = detail(0, "minY", 0);

if(@P.y == min) @Cd = {1,0,0};

In attribute wrangle, over points:

float bounds[] = detailintrinsic(0, "bounds");
if(@P.y <= bounds[2] + 1e-5) @Cd = set(1,0,0);
