Input float value from csv in Hypershade utility via mel/python script

[kanoute]

Hi,

My problem is that I want to take a float value from a csv file. I want to put this float value, in the hypershade utility "floatConstant". Especially in the "float" box. I want to do this by Mel/ Python.

The first part , how i can take the value from the csv I think that i am near. I think the MEl code is

//
string $fileName = "c:/temp/test.csv";
int $fileId = fopen $fileName "r";
//

. Do anybody know how i can do that?

Interesting question. Most definetly you want to do this with python. I'll ha e a look tomorrow if someone else doesn't have the answer readily available.

Hi

Below is my code
/////////////////////////////////////////////////////////////////////////
global proc float[] get_float_from_csv(string $csv)
{
if (!file -q -ex $csv)
{
error ("File is not found : " + $csv);
return {};
}

float $float_values[];

string $lines[] = `freadAllLines $csv`;
for ($line in $lines)
{
    string $elements[] = `stringToStringArray $line ","`;
    for ($elem in $elements)
    {

        string $match_float = `match "[0-9]+.[0-9]+" $elem`;
        if (`size $match_float` == 0)
        {
            continue;
        }
        $float_values[size($float_values)] = (float)$elem;
    }
}
return $float_values;

}
string $csv = "D:/Temp/floatvalue.csv";
float $float_values[] = get_float_from_csv $csv;
print $float_values;
