the maximum value of an attribute

[Valent]

Hi)
Can I somehow get the maximum(and the minimum) value of an attribute in VEX? I want to use them in a FIT function.

not easily. just use attribute promote sop for this.

You can fit-range an attribute with setdetailattrib() set to "min" and "max".

1st pointwrangle:

setdetailattrib(0, 'height_min', @height, "min");
setdetailattrib(0, 'height_max', @height, "max");

2nd pointwrangle:

float min = detail(0, "height_min", 0);
float max = detail(0, "height_max", 0);
@Cd.g = fit(@height, min, max, 0.0, 1.0);

Thanks, have tried both suggested variants, and I like Vex pipeline a bit more.

Remapping an attribute so its maximum is 1.0:

1st point wrangle:

setdetailattrib(0, 'height_max', f@height, "max");

2nd point wrangle:

f@height /= detail(0, 'height_max', 0);

How can I set and get in one node，because sometime need execute this every time in the loop。

The labs normalize float node wraps this up.

float value;
float values[];
string attrname = chs('attribute');
float max_value;
float min_value;

for (int i=0; i<@numpt; i++){
value = point(geoself(), attrname, i);
append(values,value);
}

@min_value = min(values);
@max_value = max(values);

use one point wrangle and done
