How would you convert a world space coordinates into a local space coordinates of an an object?

Thank.

I'm not sure why you would want to do this; what specifically are you asking for? A position in world space is the same whether you are in local or world space. Just don't multiply it by the matrix of the local space. Or do WorldPoint - ObjPos to get a vector from the object to that world point. I believe you could also multiply the world point by the inverse local matrix, but my memory about this is a little fuzzy.
Is that what you needed?

Exactly what I need.
Thanks.

Vec global;
Vec local=global/obj.matrix();
global=local*obj.matrix();
