1. A method of visualizing and correcting alignment errors between 2D and 3D data sets in an implant planning tool, the method comprising: receiving a 2D data set; receiving a 3D data set; and displaying a textured view that is generated by providing a given display indication on a surface of the 2D data set as a function of intensities of one or more spatial points at which the surface intersects the 3D data set, where the textured view illustrates an alignment between the 2D and 3D data sets.
