Abstract
A method for mapping a 3D surface that contains a volume in space, the method including: acquiring 3D vertices representing the surface, and defining in the space a first plane cutting the volume and a second parallel plane, external to the volume, thereby partitioning the vertices into a first set not between the two planes and a second set located between the two planes. The method further includes projecting the first set vertices onto the first plane so as to generate first projected points therein, and projecting the second set vertices onto the first plane while translating these vertices in respective directions parallel to the second plane by respective translations responsive to respective distances of the second vertices from the first plane, thereby generating second projected points in the first plane. The first and second projected points are displayed as a 2D representation of the surface on a screen.
