> lets say we have a cap and I want to generate a human image wearing that same cap

Do you have an image of the cap in the right orientation, as it would also appear as it is sitting on someone's head?

If not, any algorithm is necessarily going to have to invent what the cap looks like from another angle, making up details on any previously-hidden side and guessing at the depth of different parts of the still image in order to rotate it into the right orientation

If yes, crop it out and paste it onto the target head
