Method and system for generating a multidimensional surface model of a geometric structure

A system for generating a model, the system comprising a processor and a memory storing instructions executable by the processor to:

• acquire a first set of location data points from a catheter equipped with a sensor;
• generate a first surface model from the first set of location data points, the first surface model representative of a first region of a structure of interest and enclosing a first volume;
• acquire a second set of location data points from the catheter equipped with the sensor;
• generate a second surface model from the second set of location data points, the second surface model representative of a second region of a structure of interest and enclosing a second volume;
• define a bounding box using a location data point included in at least one of the first and second sets of location data points;
• calculate additional location data points based on the location of the location data point to obtain calculated location data points;
• alter a dimension of the bounding box to include the location data point and the calculated location data points;
• and
• generate a voxel grid over at least one of the first volume and the second volume, the voxel grid comprising a plurality of voxels.

• generate a composite surface model of the interior surface of the heart comprised of the first surface model and the second surface model joined together, wherein the composite surface includes a multi-faceted surface;
• and
• decimate a number of facets of the multi-faceted surface.
