(MEL)Help finding Volume of unenclosed mesh

[absoluteKelvin]

I know using computePolysetVolume will find the volume of  a mesh thats closed. But What if I need it for a mesh thats has open border?

{
    float $bBox[] = `polyEvaluate -boundingBoxComponent`;
    vector $bBoxMin = {$bBox[0], $bBox[1] ,$bBox[2]};
    vector $bBoxMax = {$bBox[3], $bBox[4] ,$bBox[5]};
    
    vector $subVector = $bBoxMax - $bBoxMin ;
    float $volume = $subVector.x * $subVector.y * $subVector.z; //basic math for calculating volume length x width x height
    
    print $volume;
}

This is my attempt. But failed badly. for some reason a smaller object yields are greater number with this code.

Hi @absoluteKelvin 

Thanks for posting! @mspeer, I see that you helped them out in their other post in the main Maya forum 🙂 Any thoughts on this one as well?

Hi!

The order/assignment of the bbox values is wrong, it needs to be:

vector $bBoxMin = {$bBox[0], $bBox[2] ,$bBox[4]};
vector $bBoxMax = {$bBox[1], $bBox[3] ,$bBox[5]};

Hi @absoluteKelvin 

Did you have a chance to review @mspeer's suggestion? Did this work for your project? 🙂
