    I want to ask how the code (comp.InverseWorldPositionMatrix * toComp.WorldPositionMatrix * locationMatrix) multiplies these three to get newMtx and then take the Y and Z axis coordinates.
    I see that the value obtained by newMtx is<vcMatrix object at 0x0000000034A089D8> but I can’t understand the meaning.

    Hy,

    If you search the vc-help you can find out that the “*”-operator is a matrix multiplication. Find details about this mathematical operation by searching the internet.

    In the vc-help you also can also find python method which is called “printMatrix”, maybe this is helpful for you?

    Regards

    Thank you for your guide to printMatrix usage.
    I want to ask what comp.InverseWorldPositionMatrix, toComp.WorldPositionMatrix, locationMatrix are defined. I have a view on vc-help that I don’t understand.
