Finding the minimum and maximum values of an attribute (VEX)

Example: Knowing the minimum and maximum values of an attribute can be helpful in a situation where you want to remap the attribute with a fit() or efit() VEX function.

This can be useful if you need to fit attributes in the middle of a vex script. Creating attribute arrays can get heavy and slow so in most cases it’s better to use this method of promoting attribute min and max values to detail: Procedural Attribute Remap

Logic around the script:

• Run over points

• read the values of the attribute with a for loop that iterates over all the points of the input stream

• append the value to an array consisting of all the values of the attribute

• read the minimum and maximum values of the array with min() and max() VEX functions

• store the minimum and maximum values to variables or point attributes depending on the need.

Script:

float value;
float values[];
string attrname = "name";
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);
