Illustrating a three-dimensional nature of a data set on a two-dimensional display

A method of illustrating a three dimensional representation of a structure with a two-dimensional display screen, comprising:

• moving a position element through a heart of a human to collect a plurality of map data points;
• generating a map representing a three-dimensional surface of the heart with the plurality of map data points;
• selecting a region of movement;
• moving the virtual camera relative to the selected region of movement;
• and
• displaying with the display device a plurality of virtual camera perspectives of the generated map based on moving the virtual camera.

A method of illustrating a three dimensional representation of a structure with a two-dimensional display screen, comprising:

• storing a plurality of map data points defining a three-dimensional structure;
• rendering a map surface representing an outer extent of an internal wall of the three-dimensional structure;
• selecting a region of rocking;
• rocking a virtual camera around the region of rocking;
• and
• displaying a perspective of the virtual camera of the rendered map surface on the display device.
