1. An apparatus comprising:
an input configured to receive signals from a catheter, wherein the signals are indicative of measurements taken by the catheter inside a heart chamber;
a processor configured to:
(a) convert the signals into coordinates of points defining a model surface modelling a three-dimensional surface of the heart chamber; and
(b) apply a transformation to the points of the model to transform each of the points to a corresponding point of an unfolded model; and
a display for displaying a view of the unfolded model,
wherein the transformation has the effect of transforming a notional closed surface centred on a reference point within a volume surrounded by the model surface to a notional open surface such that for each point of the model, a normal distance between the notional closed surface and the point is substantially equal to a normal distance between the notional open surface and the corresponding point of the unfolded model.
