This sop does a for-each process over each piece to calculate the volume. This allows you manipulate the pieces for a rigid body sim based on size. Deleting the smallest pieces that would be free radicals in the sim. Alternatively you can prefix, or suffix a size component to the pieces, so you can apply different forces in the simulation based on name. i.e. piece1_small have the force group applies as *_small. The volume of a polygon is the volume of the pyramid defined with the polygon as the base and the specified point as the apex. This volume is signed and can be summed with those of other polygons to get the actual volume of a 3D object. This summation can be done with an Attribute Promote SOP. This node is a collection of the above steps from the measure sop.
