Claim 0:
1. A system for navigating to a target, the system comprising:
a catheter navigable within a patient's airways; and
a computing device operably coupled to the catheter, the computing device configured to:
generate a view using a three-dimensional (3D) rendering of the patient's airways by executing a first transfer function for a first range from a location of the catheter to identify one or more airways within the 3D rendering and executing a second transfer function for a second range from the location of the catheter to identify one or more targets within the 3D rendering, the second transfer function configured to distinguish between a density of the one or more targets and a density of structures other than the one or more targets,
wherein the second transfer function causes the generated view to omit structures other than the one or more targets located beyond the range of the first transfer function to avoid obscuring the view of the one or more targets within the 3D rendering based upon the differing densities between the one or more targets and the structures other than the one or more targets.
