How do I calculate the Volume of an Object?

MAXScript Frequently Asked Questions

There is currently no access to the Measure Utility from MAXScript, but you can use the following MAXScript function to get the same results:


fn CalculateVolumeAndCenterOfMass obj =


Volume= 0.0

Center= [0.0, 0.0, 0.0]

theMesh = snapshotasmesh obj

numFaces = theMesh.numfaces

for i = 1 to numFaces do


Face= getFace theMesh i

vert2 = getVert theMesh Face.z

vert1 = getVert theMesh Face.y

vert0 = getVert theMesh Face.x

dV = Dot (Cross (vert1 - vert0) (vert2 - vert0)) vert0

Volume+= dV

Center+= (vert0 + vert1 + vert2) * dV


delete theMesh

Volume /= 6

Center /= 24

Center /= Volume




--Call the function on a geometry object - the result will be a list

--containing the Volume and the Center of mass in local space.


theVolAndCom = CalculateVolumeAndCenterOfMass $Sphere01

--To get the world space of the Center of Mass just like in the Utility,

--you have to do some extra work:


theComInWorld = theVolAndCom[2] * $Sphere01.objectTransform
