1. A computerized method for clone-brushing in a 2D image comprising a) specifying a first world plane in the 2D image; b) providing a source position and destination position in the 2D image; c) using a computer, identifying a destination region in the 2D image relative to the destination position; d) using the computer, determining a source region in the 2D image relative to the first world plane and corresponding to the destination region, using the source position and the destination position; e) using the computer, transforming 2D image information of the source region to 2D image information of the destination region such the perspective of the 2D image relative to the first world plane in the destination region is maintained; and f) using the computer, painting in the 2D image by copying the transformed 2D image information to the destination region.
