1. A method for producing an image of a heart chamber surface, the method comprising:
transforming a source 3-D model of the heart chamber surface into a flattened model comprising details of the heart chamber surface represented as relative differences in depth over an unwrapped and flattened surface, wherein the flattened model represents a width, length and depth of the heart chamber surface and transformed positions of the source 3-D model of the heart chamber surface defined between a contiguous first edge projecting about a lumen to a contiguous second edge, wherein the first edge is a representation of a proximal contiguous edge and the second edge is a representation of a distal contiguous edge; and
producing an image from the flattened model,
wherein the details of the heart chamber surface include an indication of an ablation path extending between a first ablation lesion and a second ablation lesion.
