The invention is related to a method of determining a model which describes at least part of a real object, which comprises the steps of: providing a first image of at least part of the real object to a first processing device, wherein the first image is captured by a camera, sending at least part of the first image to a second processing device which is physically separate from the first processing device, determining on the second processing device a registration between the first image and a first model provided on the second processing device according to the at least part of the first image received at the second processing device, determining geometric information for at least one pixel in the first image according to the registration, sending the geometric information from the second processing device to the first processing device, and using at least part of the geometric information received at the first processing device together with at least part of the first image to determine on the first processing device a second model comprising geometric and material information which describes at least part of the real object.
