The invention provides a method for producing an image 7. The method comprises recording a first image of an object 4 of known dimensions, measuring the position and orientation of the object within the first image and superposing a second image 9 over the first image. The second image 9 comprises a view of a virtual model whose position and orientation are determined by the position and orientation of the object 4. The virtual model comprises both a visible portion and an occlusion portion, with neither the occlusion portion nor those parts of the visible portion covered by the occlusion portion being shown in the second image 9.
