How to calculate moment of inertia?

If I have an assembly where different parts have different colours, and each colours corresponds to a density, is there a way to calculate the MoI about a particular axis?

I guess your question regarding CadQuery is how to get the volume of an object so that you can calculate the moment of inertia? That would be cq_object.val().Volume()

No I need to calculate the MoI of an assembly of objects with different densities. If the object is homogeneous I can just call matrixOfInertia()

You'll need to implement this yourself
